Why doesn't someone ask RMS/FSF for advice?
Those interested in copyright (and -left) issues, might want to join the UPD-discuss mailing list from the Union for the Public Domain, http://lists.essential.org/mailman/listinfo/upd-discuss
Copyright issues are not trivial. Copyright law exists because of various historic reasons, which are not completely relevant today. Even the GNU GPL, while it has served well for more than a decade, has its limitations and works best for entire software applications. The special needs of separately distributed software libraries called for the creation of LGPL, and the special needs of separately distributed software documentation called for the creation of GNU FDL. I should be really surprised if any of these license texts were perfectly applicable to the new situation of Wikipedia. It might be useful to ask RMS/FSF for advice, but he/they might also need advice from us.
