I have no idea how long it’s been going on (less than a week I would think) but if you read any MarketWatch articles, you’ll notice that the quotes now update dynamically! I was reading this article about Google (and other dot-coms)  and if you look, the quotes update! It’ll flash a light red if it went down and a light green if it went up. Also, if you hover over the ticker, it’ll pop up a little window giving you all sorts of useful data as if you just pulled up a quote. Very nice new features.
