I just found [[Open-Site]] listed on orphaned articles. I was about to delete it, because it looked too much like some newbie trying to describe (and rename) wikipedia. But, I made a Google-search, and found a free, categorized encyclopedia. It only contains a few articles, though.
The layout is nice, and they seem to have it organized (more than wikipedia, that is ;-)
IMHO they're technically too different to merge (categories etc). But maybe this could merge with Larry's "sifter" project?
