I suspect that people here have more of a problem with willpower/motivation than average, so they press "upvote!" on anything that promises, however vaguely, to solve their problem.

It has always seemed to me that the Less Wrong community treats akrasia like a problem that needs to be solved rather than simply a flaw that needs to be avoided; this, and the fact that krasia is a sort of rationality, seem to explain why we discuss it so much.
