Definitely. I disagree with Connection_ICA - many storygame authors read the comments on their storygames, if not for the constructive criticism or praise then for entertainment. I don't know for sure which authors look over their comments and which do not (aside from EndMaster, who does, and Connection_ICA, who doesn't), but I'd wager that the vast majority of good writers on this site check in on their storygames to read feedback.
One of the reasons for having comments is so that authors can see where they've gone wrong and what they've done right and improve their writing skills by acting on this feedback.
