You can keep your Kanye vs. expensive camera and Lou Lumenick vs. Roger Ebert smackdowns; I'm quite enjoying the feud between Philebrity and Johnny Goodtimes. The arguments mostly boil down to "Quizzo is for losers!" on the one side and "Hipsters suck!" on the other. I'm more of an Irish John partisan myself, but I have to side with JGT on this one.
Also, check out the comments, where Atrios has unleashed his minions on an entirely tangential matter. This thing threatens to consume the entire Philly blogosphere, and I will once again be stuck watching on the sidelines.
