Particularly as you might need to delete articles some day. Better to have an explicit "rank" you can set so you can organize your articles in the order you like. Or to have a "whatdate" time-stamp to organize them by the date they were published.

If you have designed your database properly, they will not be that much more expensive than your single query, because it's a very simple query and you only run the 3 queries once on a page.
