Sometimes you choose which social app to open based on

  • who you want to talk to
  • who you want to hear
  • what you want to talk about

Sometimes you’re just shouting into the void. At those times, I figure I’ll choose the void that feels less exploitative.

That’s part of why I still have a blog. And why I post more on Mastodon, while Twitter is mostly auto-shares from my other networks, retweets, and occasional cross-posts.

(And politics, because I’d rather keep that on Twitter, where it’s sort of the main topic anyway, than on the network that’s still fun. Not that Mastodon is apolitical. Far from it! But it’s a lot more varied than the overwhelming focus on US partisan politics I see on Twitter. And the culture and structure make the discussions at least somewhat less train-wrecky. Most of the time.)

Update: If you’re interested in checking out Mastodon and the Fediverse, good places to start are JoinMastodon.org and JoinFediverse.wiki.

An orange ring in the blackness of space

How cool is it that we now have an actual image of the event horizon of a black hole! More precisely: it’s the glowing accretion disc of matter falling into the black hole, and the event horizon’s silhouette.

The Event Horizon Telescope, actually a worldwide array of telescopes, used interferometry to effectively create a planet-sized telescope to see the light around the supermassive black hole at the center of M87, a galaxy 55 million light years away.

I remember talking with a college classmate about giant interferometry telescopes back in the late 1990s. It’s incredible to see the technique actually making discoveries like this!

What we’re seeing in this image isn’t a top-down view of the accretion disc, but an angled one — think of Saturn’s rings — and the gravity of the black hole is bending the light from the disc. Phil Plait has a great article on the science behind the image. Katie Mack has a Twitter thread on how the image was produced, why the ring looks the way it does (it tells us which direction the disc is spinning!), plus simulations of this type of black hole seen from different viewing angles.

Here’s a paper talking about the history of black hole images, with a detailed discussion of what you should expect for the “shadow” image we’ve just seen. Check Fig 12, with renderings of shadows for disks at different angles arxiv.org

Forbes makes the excellent point that, while we’d seen a lot of circumstantial evidence for black holes over the last few decades, this confirms that they exist.

What’s the minimum viable blog feature set these days?

  • Rich text posts (output; the source can be anything)
  • Titles
  • Permalinks
  • Tags/categories
  • Navigation
  • RSS feed
  • Images hosted locally
  • Media embed (remote or local?)
  • Author info for multi-author blogs

I won’t back down on RSS/Atom, because there’s SO MUCH you and subscribers can do with it.

I also think images should to be built-in and not something you bolt on clumsily afterward.

Not sure if I’d consider comments part of the base level.

What else am I missing?

Candidate Software

Looking for something lighter weight than WordPress.

The last time I tried Plume and WriteFreely, they didn’t support images, though IIRC you could embed remote images in at least one.

Static site generators I’ve tried like Jekyll require you to bolt on separate commenting systems like Disqus, or jump through hoops to roll your own in a way that will re-generate the site when someone comments…and you still have to reinvent spam filtering.

“Babylon 5 was the last of the Babylon stations. There would never be another. It changed the future … and it changed us. It taught us that we have to create the future … or others will do it for us. It showed us that we have to care for one another, because if we don’t, who will? And that true strength sometimes comes from the most unlikely places. Mostly, though, I think it gave us hope … that there can always be new beginnings … even for people like us.”

— General Ivanova in Babylon 5: “Sleeping in Light”

It seemed fitting.

While Google+ was never a shining beacon in cyberspace, it spanned the period from when social media was still new(ish) and exciting and hopeful, to when we started realizing that the big tech silos — Google, Facebook and Twitter especially — have been creating the future for us, one recommendation algorithm at a time…and it’s a train wreck.

We need to create our own online future.

We need to care about the people at the other end of the connection.

We can find our strengths, and build up others’.

And there can still be new beginnings.

In the last few months:

And Google+ has less than two weeks left before Google pulls the plug on it.

Back up your social media accounts! Most sites have some sort of archive utility, and even if what you get isn’t suitable for moving to another site, at least you’ll have a copy in case they change their business model, screw up a data migration, get washed away in a flood or just shut down.

And if you can, consider donating to the Internet Archive to help protect other sites you rely on or would just like to see again. Websites go offline every day. Sometimes even the big ones.

As you’ve probably heard, Twitter is planning major changes, and is testing them in a prototype app.

Threaded conversations are good, though I think the UI here still needs polish.

Hiding the interaction buttons until you click on the post: Yeah, it might make people think a little more. Putting some friction into sharing can improve the signal-to-noise ratio. (Also, I could swear I’ve seen something discussing this UX choice somewhere before, not necessarily for Twitter, but I can’t place it.)

Hiding the like/retweet counts: I know it was a deliberate decision to do that on Mastodon to discourage timelines from being too much of a popularity-contest. But it’s not clear how effective it’s been. In fact Mastodon recently added reply counts to its timeline (though boost and favorite counts are still behind a click). There is some value in social proof. Even if in a lot of cases it just amplifies how popular (or unpopular) something is to start with.

It’s not clear whether Twitter intends to hide the like/retweet counts completely, or keep them with the buttons like Mastodon does. Either way, I can’t imagine they won’t keep those numbers visible at least to the original poster. At some level they’re all about the metrics. And as Slashdot pointed out way back when they introduced karma: if you provide an actual number, people will try to optimize for it. Update: Buzzfeed indicates that the metrics are visible when zoomed into a specific tweet. In that case, you can still gauge its popularity or awfulness ratio, you just have to be motivated by the tweet to look for them. Essentially, it’s on the title page instead of the cover.

Camera features: There’s not really much I can say about these, since I tend not to post directly to social media in the first place. I like to take a picture (or several), then wait until I have time to crop, adjust, think of a caption, etc.

So on balance, these things might help a little.

But if Twitter is still going to be driven by showing you a timeline in most-likely-to-engage order — especially if those hidden replies are chosen in a way to encourage engagement — it’s still going to be a train wreck. Just, maybe with fewer things on fire.

Like many people, I’ve moved away from Facebook over the last couple of years. I haven’t deleted my account, but I only visit once or twice a month, and it’s been a long time since I’ve posted there. And like many people in that survey, I’ve come to prefer Instagram to Facebook. Friends and family seem a bit more relaxed there, and I follow interesting photographers rather than “brands” that are trying to sell me something.

But lately, it feels less like a photo sharing space and more like an ad delivery mechanism. Less like its own thing and more like Facebook Lite. Every time I visit, I remember Facebook will cheerfully squeeze every drop of monetization potential out of it and keep going. Every time I post, I remember that I’m handing personal data to a company that has been caught misusing it over and over again.

It just doesn’t spark joy anymore.

Where next?

Instagram has been where I post in-the-moment* snapshots, alongside Flickr for albums and my better photos, and my blog for topical images. I don’t want to flood either of those with random snaps. Twitter and Tumblr aren’t terribly appealing at this point, either.

Mastodon takes up some of the slack. I’ve found a great community of photographers at Photog.Social, but it’s more of a place for curated shots. I have a general account at Wandering.shop, and I’ve started posting amusing pictures there, but it doesn’t feel like the right place to post snapshots.

I was an early adopter of Pixelfed, jumping on as soon as it went into public beta. It’s designed to fit the same niche as Instagram, only with a decentralized volunteer model instead of attention-based ads. Even better: I can post photos on Pixelfed and boost them directly into Mastodon instead of cross-posting duplicates. But the community is still small. It’s at the stage where it feels like you’re shouting into the void because there aren’t a lot of people listening, rather than because there are a lot of other people for them to listen to.

At this point, I’m cross-posting photos across way too many accounts. I need to simplify. What I think I’ll do is reduce the number of places I post, and then pare down who I follow on each remaining site to the point where I can check in once in a while and it feels like I’m checking in on the people, not the service.

You can find me as KelsonV on Flickr, on Instagram, on Pixelfed, on Wandering.shop, and on Photog.Social.

*More or less. Sometimes the moment was three days ago.
