The March 8 episode of The Microsoft ISV Show on the broad topic of Collaboration has been posted.

Gurdeep Pall, who I interviewed in a recent issue of Message (see Evolution and Revolution: Real-Time Changes Everything), discusses real-time opportunities for ISVs, and Sim Simeonov of Polaris Venture Partners talks about a number of venture angles in collaboration, including social networking, instant messaging, and other collaboration plays.

Note: Polaris has not yet invested in any social networking company, but Sim's observations about trust and proximity services "buried in the core infrastructure of a major player" are way ahead of the market curve and worth hearing. I also agree wholeheartedly with his comments re: "failing quickly" as an indicator of smart investing: find out as quickly as possible that a business model doesn't work.
