Blog or Wiki?

Cant decide whether you should use a Blog or a Wiki to collaborate more effectively? Well fear not the answer lies here without giving the game away if one or two people are providing content, use a blog; if many people are providing content, use a wiki...oh damn I just did.

Anyway, brillant, why didn't I think of this test! I could have renamed it MBVWT the Mullan Blog Versus Wiki Test, too late now darn it!
