Reading your customers' blogs is a great way to keep your fingers on the pulse of their experiences.

I use a service called "Twitter" where I 'follow' a guy named Jerry Colonna.
Jerry was partner in Flatiron Partners with one of my favorite bloggers, Fred Wilson (they funded GeoCities and TheStreet, among others) , and I consider his insights (some of them, at least!) to be relevant when it comes to technology/trends.

Now, in the spirit of positive blogging, I'll push this over to some friends on the Vista team and see if they can help him.
