I've just started using it and although initially I thought it would be quite dull and pointless, I have discovered the world of fake accounts. @michael_bay and @foxmovies are pretty funny. Choice quotes:
"I juggle apples every morning"
"Whatever 2009 brings, we still must consider Mars a hostile planet."
"Casting for Bad Boy's 3. Getting pissed Bernie Mac isn't returning my calls."
"Don't be ridiculous - we just want Watchmen to be as great as League of Extraordinary Gentlemen was."
"What a great year for Fox: Meet Dave, Meet the Spartans, Nim's Island, The Happening, Space Chimps and more! 2009 will be even better!"
"We're not sure how Slumdog Millionare and The Wrestler slipped through, but don't worry we'll see that sort of thing won't happen again."
Are there any other comedic accounts around?
