Should I Shutter Old Articles?

When I set up MMO Fallout, I of course had the hopes and dreams that the website would last for a number of years, so I immediately started planning long term. One issue I decided upon early was that I would set the system to automatically close comments on articles when they hit their first birthday, so as to prevent comments down the line of “this isn’t the case anymore,” when the article the person is commenting on is long out of date.

I have been declining and deleting comments that specifically mention the article being out of date, as they are neither constructive nor worthy of discussion. Doing so is against my own policy, but they were starting to litter the comment box on some of my older articles that didn’t meet the one year specification.

So I’m stuck between two decisions: I can stick a warning on older articles that the information may be out of date, or I can go along with my other plan, to reduce the comment closure date to six months after posting. I like the first one, personally. It means more work, but I think it’d be worth it.

Any thoughts?
