It's cool. I've been on mastodon before this, so I get the whole "looking around to find communities" thing. Lemmy seems to make it easier to find popular communities than Masto though, so that's nice.
But... After reddit fell, I took it as a sign that I need to get off the social media wagon wheel. I was spending almost every waking minute on reddit or twitching to get on it. I hope it doesn't get like that with Lemmy, though I fully expect it to.
