I was surprised to find that there is a Wikipedia article on Conspiracy Theories about Barack Obama.
It’s a pretty good article with a wealth of references. I corrected a couple of small errors and updated a couple of things.
This exercise was occasion for a little though on the differences between blog publishing and Wiki publishing. One major difference is that a blog can be planned since it is the work of a single person or group, whereas a wiki grows organically. Also comments are more out front with a blog.
