You will have to pay for it though.
That said, I wish they featured some random pages or categories from their homepage. I'd like to see what communities already exist around the topic of my project.
Because it's a smaller community with no "algorithm" intentional discovery actually happens. I use hashtags to find stuff, and other people have found my stuff via hashtags! I only started sharing online this year and so that second bit is huge - it's night and day between twitter and cohost[1].
The site actively tries to avoid the status games that other social networks play. You can't see follower counts or like counts (including your own) and instead get notifications like "several folks liked this" (with a list of who did). There's no easy way to answer "how big is this person's following" when looking at their profile.
I think this adds up to a site that feels more like a community. Comments are typically either nice/encouraging or interesting and folks comment a lot. It's easy to find cool posts. Not having metrics is freeing. Many of the folks that post are there to share the cool things that they do.
It's not a replacement for twitter, but it's easily the site that I'm the most excited to share stuff on - especially early WIP stuff (I shared something fun last night!)
[1]I shared an early version of Flappy Dird[2] on cohost and got some real engagement and it felt great. Flappy Dird ended up doing pretty well on HN; I doubt I would have polished it as much without the early cohost support. [2] https://eieio.games/nonsense/game-11-flappy-bird-finder/
It's a free alpha. The finished product will be paid (but cheap) for those who want to post.
But it's not for porn if that's the sort of photos you want to post.
When I looked for this 11 years ago, tumblr was the only platform ticking these boxes. I just wanted to share a link to photos of what we are up to with family and friends without asking them to register at another platform, and only tumblr allowed that and did not look as if it would close shop within two years.
Looked again recently and it still seems to be the only platform filling that overall „niche“. Also it has a clean and good user interface, and is customizable to the point of changing the HTML. I hope they can save or otherwise sustain it.
Other social media attempts to constantly distract and emotionalize me to keep me hooked. Looking at a good art or photography Tumblr feels like relief now honestly.
