My girlfriend is having an affair with Twitter. She's addicted to it. You can guarantee she will be reading it now. No matter what time of day it was when you read those words. I'm not quite as deep into it but I do enjoy an odd tweet.
One particularly odd (but funny) tweeter is this bloke: http://twitter.com/NawtyDanny
It's a parody of Danny Dyer. It's laugh out loud funny.
Alan Watts: http://twitter.com/alan_watts
A passable quote machine based around the late Zen master.
Armando Iannucci: http://twitter.com/Aiannucci
Very funny comedian.
Tony Robbins: http://twitter.com/tonyrobbins
Self help guru. Seems like a good bloke.
