There are slews of new press releases about new map-based websites. Most are "just another" map of hotels or homes for sale. I like the name Mapplr and the PR describes the site as: "Mapplr (www.mapplr.com) is a publisher of hip and stylish hotels, restaurants, and cafes worldwide."
The most interesting thing: no maps. Yes there are lists of favorite hotels including pictures and links, but no maps. I guess they missed the trend of maps being a requirement for such sites.
