Yes--but not for a startup/hacker group. I brought a wiki into the enterprise to help manage my team of developers, support staff, testers, and product development. We use MediaWiki- www.mediawiki.org Our experience has been excellent. Everyone, even the non-techie business users got used to using it quickly, and now use it all the time. I've created the "home page" of the wiki to be a dashboard, such that a list of projects and their statuses, people's tasks (working and todo), and important milestones are visible for all to see. Furthermore, I've encouraged the entire team to go into other's "buckets", pull work to do themselves and feel free to push work to others should they feel someone else is more competant or has more cycles to handle tasks. Everyone loves it.
