For many years I loved Yahoo Finance. It was one of the only sites I used every single day, and the only Yahoo property I used with any regularity at all. But increasingly, I get angry when I go to the site. So from now on I'm throwing my support (read: eyeballs) behind a lesser-known Chicago-based company called YCharts in Don Quixote-like hopes that one of two things happens: Yahoo eventually gets under fire enough it fixes its product or someone else (hopefully YCharts) finally builds a great alternative for free, detailed, reliable financial information.
