Honestly, I don't see anything wrong with voting on your own blog posts. If you don't think they are high enough quality to vote on, why are you writing them?
99% of people here can't get to Hot/Trending without at least voting on their initial post, because the pending rewards have a lot to do with visibility.
I don't like instituting rules that only apply to users of an arbitrary size, so I find it hard to rag on self-voting on blog posts.
I know I get your point, you seem to very much more experienced in here than I am, I'm gonna apply your advise from now on, thanks for taking time to answer and explain.
I'm happy I could help out!
