I'm convinced that for Wikipedia to be a feeder for a free, open source encyclopedia WHICH READERS CAN HAVE CONFIDENCE IN, we must have some sort of certification system. Again, precisely what that system will be, I don't know. I'm a software engineer, and I can't predict the design of a system before I start coding it; just knowing the requirements is never enough.
The first thing I'd like to try would involve /specific versions/ of Wikipedia articles, which if I recall correctly was central to Larry Sanger's "sifter" proposal. This, of course, raises the question of how we decide which version to certify. But, being a software engineer (and a very confident, optimistic person :-) I see no reason not to go down that road even if I can't see past the first turn.
Two roads diverged in a snowy wood And looking down one as far as I could . . . I took the road less traveled by, and that has made all the difference.
