I also agree....almost a year ago this problem was actually discussed on the SO podcast (people doing the instantaneous one liner reply in order to get upvotes asap, the problem somewhat originated from a blog post someone did one specific ways to game the SO rep system).
I have a similar problem in that I ask questions that are generally "harder" and don't often have a perfectly black and white answer, but I'll get a few "little effort" answers and then they go dead, and I am left with a poor answer acceptance ratio. If I ever eventually figure out a question, I always go back and answer it myself, so really I'm trying to do the right thing as I am a big believer in the site, but I think it misses subtleties like this. It's not particularly easy, but I think they could improve things to stop gaming of the system.
