I don't actually use #Linkedln for anything, don't really know anyone who does, but I still have an account from ages back.
The other day I got an email suggestion "follow Barack #Obama!" and I'm thinking now why the fuck does that dude need a LinkedIn account? He's not looking for a job - he already sold us all out to make his fuck off money - even if he did, we all know his job history. Like, what?
