There is no harm Two (or what your suggestion implies, N) nearly identical interesting things on the front page is less interesting than two different interesting things on the front page. This is, in fact, a problem that afflicted HN more or less right off the bat as it does any crowdsourced link aggregator - Erlang days, etc. It is, as you say, entirely predictable and crushes interestingness.
