At Reddit's size, wouldn't that just shift the problem from looking up votes to looking up lists? Millions of users times millions of articles? Seems like a fast way to get an early "no" would still be useful.

Your looking it up once per page vs. once per comment. So, yes it might be faster, but when something takes 1% of total time speeding it up has massive diminishing returns.

  Still, 1% of a very large number (I don't know Reddit's server costs) can be a large enough number to be worth pursuing.

    Agreed, HN uses 1 server and /. had 4 so I assume Reddit is of a similar size, but if they need a bunch of HW then sure it might be useful.
