About 2/3 a day if that, usually less. I've only updated it once today and it somehow caused an argument;

Dear God, give us back Oscar Wilde and we'll give you a BOGOF offer of Justin Bieber and Paris Hilton."
It's usually because some ignorant git on my list always storms in with his opinion when he doesn't agree with what another friend said.. ugh.
Twitter, I update once every few days.
