Boffins from MIT have released source code for their socialbots

“you can now play from the comfort of your own home and rig up your own automated social-influencing bot too”

The source code arises from a challenge to…

“program bots to control user accounts on Twitter […] to influence an unsuspecting cluster of 500 online users to do their bidding.”

Or you might just employ a herd of cats (heh), perhaps with a LOLcat translation addon module…

Cats can tweet

“This revolutionary new toy, which was created with the help of the University of Tokyo, comes all pimped out with a camera , an acceleration sensor and a GPS, which monitors kitty’s every move, translating actions like walking, eating and sleeping into tweets”
