It looks as though the mythical good vs. evil has made it to twitter. You can follow the mythical god here and arch-nemesis satan here. All in all, god seems to tweet a bit more often than satan.
Other mythical tweeters of note:
Santa Claus
Toothfairy
Pink Unicorn
It looks like Cupid is missing, so there’s still time to claim the account and tweet away if that’s your thing….
Don’t forget Darth Vader!
