I think that post is wrong as a description of the LW crowd's goals. That post talks as if one's akrasia were a fixed fact that had nothing to do with rationality, but in fact a lot of the site is about reducing or avoiding it. Likewise intelligence; that post seems to assume that your intelligence is fixed and independent of your rationality, but in reality this site is very interested in methods of increasing intelligence. I don't think anyone on this site is just interested in making consistent choices.
Haven't had one of these for awhile. This thread is for questions or comments that you've felt silly about not knowing/understanding. Let's try to exchange info that seems obvious, knowing that due to the illusion of transparency it really isn't so obvious!
