I did this for a while, but it began to eventually creep me out that the app was asking me to input all kinds of irrelevant details about people's houses, like how many stories the house had and what style/shape of roof it had.

I get that they're trying to slurp up just some of the data a company like google gets from streetview surveillance vans, but I just don't see why any of that data has a legitimate need. I continued using the app a little while longer to fill in other details, like one-way streets in my area, but those sort of queries eventually dried up within the area I usually go for walks in.
