This was one of the first places out on the internet that I'd seen Drupal's KML module being put to good use, for example to be able to view in Google Earth all of the citizen journalist videos from YouTube that are tagged as being from the city you're interested in (e.g. Stuttgart video news and its associated KML feed of Stuttgart video news). Grass roots journalism is only useful to readers if the content is filtered to your needs, if it's in the area you want to know about and it's the type of news that you're looking for. The iCommunity.tv site does that by tagging videos by location (both coordinates and the name of the nearest city) and by topic (politics, community life, arts, etc.) and lets you filter by a combination of those*.
I heard back from Chris Haller of iCommunity.tv after posting a comment on his announcement of the site. He told me that he was previously a Mambo/Joomla user, attracted to Drupal both by its flexibility and by its geo-capabilities. It's great to see that happening, and someone told me exactly the same thing yesterday too. It's also great that organisations like the Open Source Geospatial Foundation are using Drupal as their platform of choice.
Its good to see Drupal becoming more and more of a GeoCMS and people taking the tools and finding ways to apply them in useful and practical ways.
* KML feeds for multiple tags do not currently work in the KML module, as I've just discovered
