Today's internet find is a project with amazing potential. WikiMapia can be summed up as a geographical encyclopedia with articles placed on the Earth (kind of like Catholicgauze's Atlas).
With WikiMapia anyone can edit or add places to the Google Maps mashup. It is just getting started so many places need to be added or expanded upon. But do not let the sparse, out zoomed initial page fool you; be sure to search for cities to see how in-depth WikiMapia really is.
The only problem I have noticed is that latitude and longitude are interchanged. This is a cardinal sin which upsets Catholicgauze.
