Word of Blog, a Promotion Service for Change
The badges are organized by organization name and by tags, which is very nice. If you select browse, then by tag, you'll see an example of a tag cloud system put to very good use. A tag cloud is an alphabetized list of tags used in a site, but with their sizes varying according to their frequency of use.
Thanks to the Full Circle Online Interaction Blog for pointing to this resource. I found their via the NPTech Meta Feed, a cross-platform RSS feed I created for items tagged nptech, the tag for non-profit technologists.
