We saw a steady flow of traffic all through last year on a few .christmas domains from last year's advent calendars.

I don't think they seem stale, but perhaps out of season Either way, we're committed to keep this content online for the foreseeable future, and write a new edition next year if people find it interesting.

Domains expire after a year, so it you'll always be renewing around Christmas. Unless you were referring to maintaining the site itself, which yes, probably won't have any new postings around July.
