Ask IH: Would you use a site/app to check how crowded places are?

Spotter | Search for a spot and find out how what's going on in real time.

Have you ever been waiting in line for coffee or a beer and wondered if the place a couple of blocks away is less crowded?
I'm trying to solve this problem by building a site that gathers anonymous updates and anotates them by time ranges, like 15min ago, half hour ago, and so on.
There are also photo updates, which are also categorized by time-frame.

Do you find this useful?
Any feedback is welcome!
