I was a little misinformed, the creator of Twitter (
Jack Dorsey) partnered up with
Evan Williams and
Biz Stone and they combined, released Twitter as its own company.
Both Stone and Williams were involved with blogger, and Evan Williams was the 'creater or founder' of Pyra Labs (blogger).
Either way, these fellas have blogging, web2.0 and social sites in their blood. They as a whole are largely responsible for the popularity of such mediums like blogging, and even coined the term 'bloggers'.
