Hey, get a sense of humor! Jeez...
Really, it's pretty hard to diagnose such a vague complaint, and seeing as how you've just reinstalled shifters (and presumably cables & housing???) there are a few suspects.
BTW, a friendly photography tip: try that same shot from further back, but fully zoomed in. It'll get rid of the fisheye distortion and have a better chance of being in focus. And seriously -- your seat tube looks squared off in that shot. What frame is it?
