For posts I prefer to use a few more votes than just 10*100%. I try to vote at 25% or more to so that the vote is worth something, and frankly so that it doesn't get lost and so the author will see it if they look. But then I do vote at 100% for articles that I think are really good, and sometimes for people whom I think really deserve it

For comments on my own posts I tend to upvote in the 5-15% range depending on the thought/effort that seems to have gone into it. with 0% for spam obviously

Cheers
