I think I would use some of these alternative social medias more often if they weren't pains in the ass. Mainly talking about Cohost here, they don't yet have a nice login management system so any time I log on from another device it logs the other one out.
Mastodon seems fine in that regard so far but following people off-instance sucks a lot.
I know it's important that masto/the fediverse is a semi open communication standard and not just One Company With One Website, but I don't like having to keep another tab open to copy and paste a person's URL into (and in some cases still not be able to find them to follow).
Maybe it'll pass, like any other growing pains.
