There are plans afoot to spin off Nupedia and Wikipedia into a non-profit organization. This is by no means certain, but I think that there is
much
to recommend it.
501c3 non-profits in the U.S. are severely limited in the kinds of political speech they can make, esp. in re: various candidates and issues on the ballot. Not necessarily something I would expect wikipedia to be doing anyway, but since it ''is'' something anyone can edit, you might want to look at the possibility very carefully. Even some of the comments on various /Talk pages might be enough to cause a challenge to the 501c3 tax exemption; I am not sure; I am not a lawyer; you might want to look into visiting one. :-) Just a warning, not that the sky is falling, but that you should look into it before making a decision.
