If Yahoo! ( YHOO) rolls out a new look and nobody notices, does it make a difference? Ever since Google ( GOOG) debuted its finance site to great fanfare last March, Internet investors have been waiting for the other shoe to fall. Google Finance has since been seen as a disappointment -- as TheStreet.com's Jonathan Berr pointed out , it made up less than a percent of Google's total traffic -- but it introduced features such as interactive graphs that Yahoo! would, in time, surely try to surpass. On Monday, the other shoe finally dropped. But it made a very soft -- barely audible, in fact -- thud. And it didn't come without more than its share of glitches. The new Yahoo! Finance has evolved in three ways: It now offers interactive stock charts that can be more easily customized, finance-related video feeds from the likes of CNN.com and ABC.com, and a revised interface for its highly trafficked message boards. The problem is that these changes were greeted with either resounding silence or, in the case of the message boards, anguished mewling among users who didn't appreciate the changing a format they were already happy with. Let's start with the message boards. Yahoo!'s stock boards have long been the most active online community of investors, long and short. You either love it or hate it, depending on what you're looking for. If you have a thick skin and favor anonymity, sarcasm, the caps-lock key and long, off-topic discussions designed to antagonize, then this is the place for you. If you want information and want it quickly, you're in the wrong place. Yahoo!'s new design seems geared toward less time-wasting and more information. Messages can be rated according to how useful they are, and the less useful comments can be easily filtered out. They are also sorted by thread, not simply chronological posting. You can make users disappear from your online world simply by clicking a link below their names. This was clearly intended to make the boards more useful, but on Monday it had the opposite effect. Instead of calm and order, the boards -- especially the one for Yahoo!'s own stock ticker -- were a great Kabuki-fest of revolt, outrage and hyperbole.
