Great post @katie hunter. I believe this is the correct orientation for the product too. My corporate team, (I run a corporate board), has concentrated solely on integrating with outside social services and media. as a corporate experiment. The only downside I have so far is the maintenance hours required to keep up with the ever changing API's.
Our employees have loved the changes, it makes them feel that we are up-to-date with the web. I had real concerns about opening our site up for fear of leaking corporate secrets, but it turns out our employees are well behaved and it is not an issue. Instead we have gained some great ideas and exposure from friends of co-workers on our products.
I am looking forward to VB5, positioning the product for the new market place is going to be crucial for some of it's success.
