Any interesting contacts in the gaming industry worth following on Twitter?

[Urban Xperience]

What with the age of social networking that is upon us, I thought I'd ask the community what interesting contacts in the gaming industry are worth following on Twitter? I am currently following the likes of David Jaffe and David Perry but wondered if there were any others I may have overlooked.
