Hi Nicholas, thank you for stopping by. Centiare was set up to utilize the fantastic MediaWiki collaboration/editing tool for commercial directory content.
As such, it also provides a commercial outlet for Wikipedians who wish to market/provide editing services to the many organizations who need assistance with their listings. I think you'd be surprised at the number of WPers who have checked out the site. As you say yourself: I'm waiting for something to happen elsewise.
We've added all sorts of interesting extensions/mods to extend MW's functionality, not the least being protected user-owned pages and semantic tagging capabilities. I'd be happy to walk-you through some of the basic elements if you're interested - not the least being your own directory listing. Centiare 14:44, 7 December 2006 (PST)
