itesser ink: progress, uncensored

Fellow bloggers, I know you're out there. I have a question to be answered.

How long after a post is published should the comment discussion remain active?

I know that there's no mechanical limit to how long a thread can be posted to, but surely there's some rule of thumb for the shelf life of run-of-the-mill posts. Sometimes I read posts two weeks after their publication, but feel conspicuous commenting, especially if I'm catching up for all two weeks in one day (perhaps not in order) and may be inclined to comment on multiple posts in the span of an hour or two.

So at what point is it strange to be commenting on old entries?

Or is it a matter of "who would ever refuse a comment?"
