You had me until "Quora" as a suggested alternative. If any site approaches the annoyance level of LinkedIn for me, it's Quora. Both have a habit of spamming me; their unsubscribe stuff is kinda dark pattern-y, in that it's easy to end up still getting mail from them even after clicking through to unsubscribe.

That said, I haven't used LinkedIn in years. Have no interest in it, for anything. If I needed work, I might consider going back, but I doubt it. I certainly wouldn't hire someone based on a LinkedIn profile, and I probably wouldn't want to work for someone who did.
