:Well, my user page is based on a Portal template. Portals often feature "selected articles" instead of "featured articles" or "good articles". The criteria for good and featured articles can be found through WP:WIAGA and WP:WIAFA. Of course, the criteria for selecting articles for my own user page are completely arbitrary and decided by me, but if such a guideline existed, it would probably be reachable through WP:WIASA ("What Is A Selected Article"). Hope that makes sense.
