Back when I played Ingress, most city-level activity was coordinated through private G+ communities (with neighborhood-level activity being done in Hangouts group chats), and the more social stuff (i.e., the stuff you don&#x27;t care about keeping secret from the Smurfs) tended to happen in public G+ communities.<p>LinkedIn is a good tool for viewing someone&#x27;s public resume, though I don&#x27;t regularly log into it. Every once in a while, I&#x27;ll log in to check out how a previous employer is doing (e.g. see which of my ex-coworkers are still at the company, what new positions have been created, etc.). I still have dozens of unanswered connection requests from recruiters, though (I don&#x27;t accept people I don&#x27;t know), and the site has gotten progressively spammier over the years.
