The "necroing" rule is really pretty fuzzy, and really it's more of a spam-prevention measure. If you have something particularly relevant and important to say on an existing subject, better to revive an old thread than to start a new one; the rule is there to keep people from bumping old threads with something useless like "me too" just to earn a few Aurum.

So if it's your diary thread, any diary entry that you as the original poster would make is by definition relevant and important.
