We have provided Luca with the kind of live feed that we normally only give to companies to do his research in real time, and right now he’s working to process a full dump of the English Wikipedia. I have suggested that we could then offer a MediaWiki “tab” that could show the articles with trust coloring overlay.
After my conversations with Jim Giles this was condensed into “incorporated into Wikipedia” in the New Scientist article, which is an error (we’re going to send a correction on Monday).
In other words (if you remember that minor brouhaha) the foundation seems to be doing everything just right -- they're in touch with the decentralized nature of the web, the idea of mashups, etc. Awesome.
Also, Kelly Martin is porting mediawiki to java. (Server-side java, presumably -- not the craptastic client-side stuff.)
