Congratulations to Google Maps Mania on its first anniversary. I’ve given up trying to keep track of all the hacks and mashups — my present policy is to blog about them generally, and include any mashups when talking about a general topic, but for the most part I won’t link to a site that merges this rather than that data source with an online mapping API — but it’s important, I think, that somebody keeps track of this phenomenon, so I’m glad to have Google Maps Mania with us. Thanks, Mike!
