@mattskala To be honest, I think most people use pinned posts as a sort of “greatest hits” and that's definitely annoying, at least for me. You go into someone's profile to see what kind of things they say, find out if they're worth a follow, and all you see are pinned posts from 2021. Not even introductions, just normal posts.
I'm not saying the use case you described doesn't happen, of course it does, but in my experience it's the exception, not the rule.
@mattskala To me it is, because I don't want to read that. I want to know if the profile is active, if it is interesting, not if it was years ago. The “read this first” info can go in the bio. Actually, if they asked me, I'd say that's where it belongs.
@josemanuel No doubt this depends on which part of the network you're looking at. The "read this first" case is definitely dominant where I'm looking. But even in the "greatest hits" use case, is needing an extra click in order to view them and find out, really an improvement?
