Im gonna try to use both. I just havent made a lemmy account yet. I made this kbin account like a day or two ago but couldnt stay logged in (bugged), so I browsed lemmy and thought oh, the posts look like reddit posts, and that made me happy.
Then today I just tried kbin again and it’s working now yay :) so I’ll probably make a lemmy account soon too. To me they seem similar as long as they stay in the same fediverse
