WaveBlog

WaveBlog is a location-based blogging program enabling users to communicate and exchange location and time relevant information.
Users send location-based visual and text information from their mobile phone into WaveBlog which in turn, organizes them by subjects (traffic, bars, clubs, celebrity sightings, ), dates and places.

In addition to the maps on the weblog, the RSS feed also integrates per-post geolocation to let users see which weblogs have been updated in real time near them or in another specific location ("location-based mobile aggregation").

For the time beeing, it's being sold to carriers, not to the general public.
