It is not a decent idea. It is Great idea for a side project; but I am not sure how can you capitalize it. I mean, it gives a huge value to the user, and probably there's a market for it. But, it's a free product to stay into the free zone... In order to have something in return, I guess you can aggregate that information, and look at what patterns you can find. Probably to market yourself as an expert -or- working as a reseller. Anyway it's a good job (tm) and you should be proud of it.
