Facebook, but only to play games and here on EP
facebook, twitter, and google plus
different media for different messages and audiences....
linkedin purely professionally
facebook friends and family
twitter mostly professionally, but with a more humourous and quirky note
G+ mostly on hobby stuff
ep for fun and topics I don't need my real life connections to know
all of the above :-)
Only facebook, but only about a minute each day
ep now .... help.com in the past.
None of the above, fine here on EP.
