I have to say, it is interesting to listen to the local announcers for the other MLS teams (though who they choose seems pretty arbitrary.) I'm reminded that a) the San Jose guys are pretty terrible and b) the RSL guys are pretty good. Vancouver's guys are SO enthusiastic.
And, with the last game of the night, I find myself rooting for the Timbers. Well, more rooting against Montreal - not as revenge, I just prefer that Seattle, Vancouver, and Portland stand above everyone else, and especially Eastern teams. (Except DC, because they're my second team.)
