ost_uid0]A recurring feature, yes; a daily feature, no. In other words, it should only appear if something noteworthy actually did happen X number of years ago; otherwise, you might end up with an entry that says things like, "On this day two years ago I posted a link to a virtual bubblewrap site."
On the other hand, to expand your pool of material, you could make X variable; it need not always be two years. And the material could include interesting happenings on the discussion board, such as the initiation of a particularly significant debate or a consultation of the readership's opinions on a matter of site policy (like this one, for instance).[/color
