Hi Mappers!
I just released the first official version of GeoRecorder, a small gtk-gstreamer-gpsd tool that records what you say into your microphone and stores the longitude, latitude and altitude of your current gps position into tags. Take a look at http://georecorder.silbermayr.at/

Just wrote a small blog post about Openstreetmap and mashup ideas. See http://silwol.wordpress.com/2007/09/24/ideas-for-openstreetmap-mashups/ and add your own ideas in the comments.
