It isn't 100% useless--it depends on what schools you applied to.
Also, the information is updated by the schools, so if it IS useless for you, then you should blame the schools.
The idea in and of itself is an excellent one. This is the FIRST year that it has gone nationwide, and there are aboviously lots of kinks to work out: schools not updating, only a handful of schools participating, etc.
In a couple of years InfoSource will really rock.
Several of us from my undergrad got to beta-test InfoSource and were able to go through AADSAS for free as a result--it seemed like a good idea then, but it also seems like they haven't made many changes to InfoSource since that initial testing phase.
