Meatball is a loose grouping of people who are interested in online communities, culture and hypermedia. We talk mostly on MeatballWiki and sometimes on the MeatballMailingList. The original goal was to focus on CollaborativeHypermedia but topics have ranged from intellectual property to CyberPunk to the confusion of UniformResourceIdentifiers. Occasionally, some of us bother to stop blathering and do some real work. You'll find some project journals on MeatballWiki too.
