I say that because Forrester defines Enterprise 2.0 as:
"A set of technologies and applications that enable efficient interaction among people, content, and data in support of collectively fostering new businesses, technology offerings, and social structures."
With that broad definition, any tech vendor would qualify. I mean fire your entire marketing team if they cannot get Forrester to call them Enterprise 2.0.
That is if you want to fight for a measly $ 4.6 billion Forrester estimates for the category out of annual technology and telecom spend of over $ 2 trillion.
