Maps + Mobile + Mashups + Social Media = Kmaps
KMaps is an Ajax-based site that aggregates Google Maps mashups for viewing either on a Treo smart phone (and soon a Blackberry) or a web browser. What's unique about it is that it's location-aware, social and that you can publish a Kmap using a smart phone. For example, here's a Google Maps mashup of celebrity sightings. It's empty right now, but if you had it installed you could publish a sighting using the KMaps service while you're on the go. They offer a “where is” location service as well.
In addition, KMaps offers a tool called KMaplets that you can use to create and share location-aware, mobile map mash-ups (say that ten times fast!). You can really get a sense for how powerful this might be when you look at this mashup of celebrity addresses. For more information, visit their wiki.
