These days the operative buzzwords are open and transparent. I don't advocate both of those concepts blindly but I do ask, what is the potential downside of offering this level of data to the public?

If you keep everything private then you have something to hide, better yet you have something to manipulate. Perhaps you want to go public or attract investors with your projections not your reality.

In appropriate cases this type of sharing can bring your users into your business in ways no other tactic can. Devout users want to see you succeed and this gives them that barometer.

All in all, I applaud them (assuming making it public was intentional.) Not only does it help me benchmark my business but it helps me connect with Tweetminer in a way I otherwise wouldn't.
