I find it just addictive enough. There are definitely lulls in activity, but they're short-lived and I have things I should be doing besides shitposting so it's actually helped me.
The quality, however, is much higher. This can be very subjective, but I do have some real world evidence. The number of times I'd show someone a meme and have them say "Please send that to me" has definitely gone up since I switched to the fediverse.
