A haven for armchair investors and money junkies, Yahoo! Finance has everything you need to keep up with business news, stock-specific research, charts, even press releases. In late May, Yahoo! Finance resumed free real-time quotes instead of the standard 20-minute delays on rivals like Google Finance. (The service had been suspended a couple years ago in a dispute with the major stock exchanges.) Power brokers can shell out $10.95 a month for real-time stock charting. For all the criticism about Yahoo!'s failure to innovate, its finance site showcases the best of what the company has to offer.
