I also vote comments I find I need to vote for, I never see whether it is small fish or bigger one, when I like the comment, I vote for it, when I think it deserver the SC vote (since I am currently one) I will put it in the list. And you can take a look at the vote I been giving, to draw you a little picture of the accounts I set the auto-vote for (but not all of them are auto-voted). Not all of them are big fishes, some of them even so small. I do the auto vote to make the power I have more useful, only a little decision I made to myself. Haha.
