I see a lot of value in the post, which can help a person to expose a disconnect between their normative ideal of what they should do and what they actually are doing. A large part of the point is that this rationality stuff is not just theoretical, it has practical implications, and we should remember to apply the practical lessons in our daily lives. The short, easy to remember "What are you doing? And why are you doing it?" is great for prompting oneself to examine how well they are practically applying rationality, how effective they are at achieving their goals.

I agree that the post has little substantive content, but it may generate some interesting discussion even while sitting at 0. You could fault it for timing - the flood of former lurkers who saying Hi, sometimes with interesting commentary, is already too much to keep up with - but I'd rather downvote an overly long post than a short one. Less of a strain on my attention economy.
