Dunno, Bruin . . spite?
I don't actually care, I'm just amused by it, and a little perturbed at being dicked around - more by them going back on their 'two week decision' promise then by the hold. Not only won't I get a decision until April, ut it took them eight weeks to even send the hold. The only reason I applied was I figured I'd have at least one "yes" by the new year and be able to relax. Looks like I wasted the 5 minutes it took to fill out their application.
A few friends of mine I suggested calling them up and telling them about HLS to mock them, but I'd rather wait and screw with their yeild. Well, not screw with, but rather make it honest and not manipulated.
