Another funny thing about Larry Sanger’s idea of a progressive fork off of Wikipedia is that he can do nothing, under the terms of the Free Documentation License, to prevent his expert-improved content from being reabsorbed by Wikipedia. In other words, the better the Citizendium becomes, the better Wikipedia becomes — but not vice versa. In the Citizendium (the name still refuses to roll off the tongue), forks are definitive. The moment a new edit is made, an article’s course is forever re-charted away from Wikipedia. So, assuming anything substantial comes of the Citizendium, feeding well-checked, better written content to Wikipedia could end up being its real value. But would it be able to sustain itself under such uninspiring circumstances? The result might be that the experts themselves fork back as well.
