Honestly I just jumped to Lemmy after dndmemes sent me this way and it feels like I'm delving into early internet forums back in the day, fresh and new and full of excitement for the future
Fresh optimism for the communities and the new apps all being furiously worked on right now. I’ve got Memmy, Mlem, and Voyager all installed currently and watching the rapid development of each is a hell of a lot more interesting than the one Reddit app that’s been dogshit since they bought it and stuffed it full of ads and is only getting worse.
I should just probably try them all but do you have a preferred one so far? Currently using Memmy but honestly I finally dove back into something like this after a proper year without Reddit, to see how this community is doing and to see what the vibe is like.
Remember when forums would let you put unsanitized HTML in your signature and people exploited it to flood them with pop ups and redirects? Lemmy's bringing that back, too!
I was on a forum looking for something once and someone had a flash game as their sig. It was like Portal The Flash Version but the gun was on a rail. And the dimensions of the flash viewport were like a typical sig, so it was pretty interesting just to play a game in such a strange aspect ratio. Not really relevant to anything but I haven't thought of that in a really long time.
Lemmy DID support HTML and iframes sometime ago. The devs scrapped it for security reasons and I hear they are planning to bring it back in future after making sure it is secure enough to use.
