Same, although my perception is that LinkedIn has moved past its peak usefulness, and it would be better to spend time on other platforms than creating a LI account. All I hear about LinkedIn these days is spam.
There's a lot of platforms that do sort of related things, so it's a hard thing to answer. For "finding a job" I've been looking at HN, remoteok, and a bunch of others. For professional networking I use various tools run by former coworkers (mostly Slack and Google Groups). For "blogs" I use HN and Reddit. etc. I don't think LinkedIn does any of those better (my perception, I'm not a current user).
Personally, I'm probably not interested in a LI clone for many of the reasons I stopped using LI. I deleted my LI account maybe 8 years ago, after getting too much spam (and I think some security issue?)
LinkedIn sceptic here -- I would assume that in 2022, the closer you are to real, legal Microsoft-ecosystem roles, the more useful it is.. meanwhile, the independent people in tech get splashed with mud. No comment in this discussion has indicated to me that LinkedIn is not useful for certain swathes of established professions, even now.
