It's rather therapeutic.
I couldn't really care less about facebook these days but it's nice to trim the list of 'friends'
not in some sort of nananana I'll de-friend you kind of way. I would add lots of old colleagues and stuff. I will never talk to them so I will get rid of em.
i might shut down linked in completely it's a load of *******s.
Twitter is alright as I keep it separate from that stuff.
