A9 maps was a great idea for online mapping. it interacts online users with useful information. People can submit and share their street picture. But it was gone, what a sad story!
The feature, street-level photos was so helping for me. I could easy to recognize the place I was going. With google map or others, I only can know the location, and the “top” of the “old” building which no user-friendly at all.
One thing I don’t understand is, as in the “web 2.0” age, why this good tool can not be continue? Maybe it falls into the category “great product but not great goods”.
