If I only wanted to look at pics of cats then Twitter or Instagram would do just as well. If Lemmy survives as a forum for vacuous fluff then it'll have to do so without me :-)
as near as I can tell the technology is great, but the people are horrible. Almost every interaction is unpleasant, and when I do get some interesting conversation going some troll reports me and an admin nukes my account. So I am not optimistic about the future.
