Heh

What's that French phrase about the "Wit of the staircase"?

I just took a quick look at my post from this morning about XKCD's "Map of the Internet", where I observed that

he has someone named Tam in LiberalBlogLand; are there two of them?  Shouldn't there be an Island of The Wookie-Suiters? 

and it occurred to me there should also be an Island of Misfit Libtard Blowhards.  (And maybe an Isle of Redundancy Island...)
