We seem to have migrated the Shakespeare question to literature.se where it may find a warm home, but I think a case can be made for keeping it here.
While it is clearly in a grey area where a truly definitive conclusion may be impossible and people might well want to spout mere opinions rather than facts, it would still be valuable to have a thorough skeptical analysis of the logic behind the alternative author theories. As far as I can tell many of the alternative authorship theories are based on very tenuous logic and evidence.
My view is that allowing skeptical analysis of those ideas might actually enhance skeptics.se. Of course it might just lead to an unproductive flamewar. But until we have seen what sort of analysis emerges how do we know? I'd vote to un-migrate the question until we know what sort of answers we get; if we get good skeptical analysis of evidence let it stay.
