The thing that shocks me about Linkedin is how much non work related stuff people post there. As if facebook is not terrible enough, you post politics, conspiracy theories and memes on the social media you use to look for jobs?
Those people get un...linked (?) if I notice it happening. I hate that crap - I stay away from Facebook intentionally, I don't want it on L.I. as well. Especially as I'm already uncertain that it's giving me any professional benefit given the info-privacy tradeoffs.
