You post a lot. People like @techslut know this, which is why she (I assume) only auto-votes you at 40%. Which is the same as saying that 40% of your post deserve 100% votes.
I personally choose to manually vote for you when I like what you post.
to be clear, I don't think there is anything wrong with the amount you post. I like it even. I just don't feel like voting on all of it.
