I can only see the thumbs for other people. My own posts the thumb-ups and downs I receive are hidden. Unless I swap to AdminModulous and then I get to see the thumbs up and who placed them for Modulous' posts. I can also thumb-up my own posts (as Adminmodulous I can upthumb Modulous' posts) which doesn't seem like intended behaviour.
I find that clicking on a link forty times is rather satisifying even if it doesn't really speed things up.
Interesting note RFC 5988 introduced the notion that people who repeatedly click links clearly really want the content as quickly as possible, and so many browsers will now send a http status code 418 to the server, which alerts it to this fact and sends the first 10% of the packets down the 'fast lane'.
I assume you use Safari, as that does kick in at 40 clicks in short succession. In Firefox it's 17, but then it presents an alert box, followed by a couple of browser pages confirming you really understand what you are going to do. Chrome just knows what links are important to you and acts accordingly (ie., send the 418, and sell your activities to marketers).
