So it seems like some of you might be interested in learning more about Dreamwidth.
Listen, here's the thing: Dreamwidth is not slick. It is not fancy. Its base code was originally put together some two decades ago or more, and it looks like it. It can't do much with images and definitely not with video—like, I think there's some way to embed video, but I have no idea how to do it, and hosting it on Dreamwidth is, uh...
The point is! Dreamwidth is a lot different from Tumblr. It's closer to Tumblr than it is to Facebook or Instagram, but it's a lot more old-school internet than Tumblr is. And that means that, for anyone who wasn't on the internet some ten, fifteen years ago, there's probably going to be a steep learning curve. It can take more effort to post things there, and more effort to find your people, its image hosting capacity can charitably be described as both "limited" and "poorly organized", and overall it may still never be the kind of website where you, personally, will want to spend a lot of time or do a lot of things. Dreamwidth does not and will never have an app, for pretty much the same reasons as AO3.
But there is one thing I can guarantee, and that is that Dreamwidth is willing to fight for us and our rights. They're already doing so.
If you've ever thought to yourself, "I wish AO3 were an actual social media site," consider checking out Dreamwidth; it's not too far off from that as an idea.
You can host media on squidge.org, which is specifically for hosting fandom media.
While we're on the topic, Proboards is still around, and still free, and still customisable, and still WORKS. Neocities has replaced geocities and is also pretty great (and you can host things from there too if you want).
The old infrastructure is there. We don't have to rely on for-profit social media companies that censor everything all to hell. The tradeoff is YOU can't be a for-profit social media company either. There's no 'reach' there's not 'like and subscribe' there's no 'i want my socialising space to also be my job' nope. It's just socialising.
