no, Greg F, Wikipedia is NOT a 'blog'. A blog is one persons opinion, kep & edited by that person only. Wikipedia is a collaboration of many people who can correct each other.
As I and others say above, you should still take care in using it, but it tends to have accurate information much more often than not, and unlike a printed encyclopedia, it can BE corrected instantly if better data is found.

The "Boobocracy" will be there forever, but maybe we can gradually lead them toward the BETTER internet sources.
