If I load the page after he posts the original comment and respond pointing out that the podcasting app is called overcast, an inline comment makes me look bad while the edit makes it clear that there was a context in which my response made sense.

You are right, it's just an old habit.

It's a reasonable habit by people who value transparency. It's not a matter of whether or not people care.

Keep doing it, screw the people who can somehow find umbrage at such a non-issue.

Plenty of people do it, myself included. Don't change your habits just based on one cranky old bugger.
