Link - Mashups and Web Services

“Don’t get me wrong, I love the Google API, and think that I’ve put together a pretty good application of it. But ArcWeb Public Services seems to be much more data rich and correct. Google maps (the service, not the API) can’t even find my house. ESRI can find it, show thematic data about the area, give me topographical data, display a much better satellite image, and in general is just better (from a data standpoint).”
