Around the time of the reddit protests, was looking at one of those "reddit alternative" posts that referenced Lemmy. One of the links given was to a list of servers with a short blurb on them, which included Burggit, the blurb of which made it quite clear what sort of community it was which caught my eye. I didn't have time to explore much of anything right then but a few days later when I clicked through a link in a different post to the same list, I noticed that Burggit had been removed, which had the effect of making me go out of my way to find it again (since I didn't remember the actual name).
I read some of the public posts at that time, and re-visited a few times (not having the time to figure out the whole Lemmy thing right then) to keep tabs on developments and liked the basic premise behind things and the directions things were going.
ASSTR used to be my jam.
The site went through a big crash a bunch of years ago, and then apparently suffered more subsequent technical issues afterwards. The couple times I've been there recently, it's been like doing the internet equivalent of urban exploring a mostly abandoned city.
There's some things still functional, some people still active there and eking out an existence, but lots of the site structure is broken and a lot of the collections which aren't being maintained are partially or totally broken.
