Since OpenStreetMap received a EUR 12.000 funding from Digitale Pioniers, the Dutch branch has really taken off. I’ve been pretty busy with the promotional side of it, including setting up an http://www.openstreetmap.nl weblog (in Dutch).
FWIW: I tried out WordPress, because of the GeoPress plugin, but I could not get used to WP. So obviously I quickly switched to my blogging platform of choice: Serendipity 
My geotag plugin works great with OSM btw.
