Oct 11, 2009 at 23:11 comment added Ilya Nikokoshev Indeed why not just edit it out?
Oct 11, 2009 at 19:05 comment added S. Carnahan The finite interval assertion in the last sentence is clearly false, since you can take an infinite subsequence of rationals with nested neighborhoods. I don't see a way to rescue the argument (but it's more or less moot at this point).
