Yeah I think paragraphs are great. You cut the voter group down to people who are not only good, but clearly know the implications of their vote and can tell you how their votes will affect the metagame and etc.
I just don't like the idea of forcing even more work upon players. They already do enough work as it is (well maybe not "enough" but paragraphs are a ton of work on top of what they already do). I guess it comes down to what you think is better: the best voter pool possible, or simply a good/alright voter pool that requires less of the players. I'm personally a fan of the former.
