Didn't google some time ago have these up and down arrows, like here on HN with comments, which I never quite learned as to what they were for. That is not quite far off from marking sites as spam and I used the up and down arrows only perhaps once in the entire time. Search is different from sites like this. Here we know we are going to spend some time reading interesting content, but not quite what we will be reading. When searching you know you needs some information and what you want to do is find it, preferably instantly, and get out of Google immediately. It is easier to click on the next link than mark some site for spam or click the up and down arrow.
