Social Media Platform follow up

I appreciate everyones comments and was made aware of a post by Jermiah Owyang from Forrester in which he compiled a pretty comprehensive list of white label or private label social networking platforms. Maybe this will help clarify things. I was looking at a very specific group of social media platform providers and not necessarily open source social media platforms or ready made solutions such as Ning. However, this does not mean that I am discounting the other players in the social media platform landscape.I just think that we need to segment them a little bit better since each offers a different spn and offering.
