I got to my slider yesterday! I've not yet quit 100% upvoting (I'm on holidays anyway, so reading less) but I think I will start upvoting comments on my blogs from now on, since I can do this with something like 10%, so I won't blow up all my VP too fast. Until now I didn't upvote people leaving comments on my posts since I wanted to upvote great articles. (I read so many here!) - Anyway, interesting post, and will have to see what it will change in my upvoting strategies.
