Early strips of some webcomics carry the author’s much later comments. Christopher Baldwin (Bruno) and David Willis (Roomies!) are reposting old series that ended. David Morgan-Mar’s (Irregular Webcomic!) schedule these days is two new strips and five comments on old strips each week.
If it were me, I think I’d want to keep coming back to older strips, with ever decreasing frequency. Perhaps like this:
if n even:
n /= 2
comment on n
while n even:
n /= 2
add n to backlog
else:
pick a number from backlog; remove it
comment on that entry
That’s incorrect. Irregular Webcomic runs new strips four times a week and rerun comments three times a week.
This is how I get readers to reveal themselves.
Sexy Losers (formerly The Thin H Line) also has two layers of later comments.
