I feel like I do this a lot with podcasts. I started watching the Gus and Eddy podcast and finished it about a month before the last episode was released for example.
It could be anything though. An online game, an OS, a console, TV show, a forum, or anything else. I’m just curious what people have to say.
It also doesn’t need to be “dead”. It could just be a significant change where a chunk of the community left.
Tumblr! I only joined shortly before all the wildly terrible business decisions killed it lol. Great memes from there would get cross-posted to my various platforms often enough for me to want to go, but I procrastinated until it was almosssttt too late…
Now we got a fediverse version though 😈
