Its great because its simple. Every time I think of a feature to request, I start to think that most of the time the added feature would get in the way of what I really end up wanting. Which is to quickly answer 1) what are the events going on around me, 2) what buzz if any is going on around them to help me decide if I want to go, and 3) how to get there in terms of single click directions. Quick, fast, etc. Its great because of its focus on these three things is clearly paramount.
