Seeking Alpha's Market Currents + Twitter = Best Free Stock Market News Ticker

To give you an idea about how mashing up free tools can create incredible value for users, check out the Seeking Alpha Market Currents + Twitter combo.

Market Currents provides minute by minute updates of important stock market news at their site. It updates automatically at the site. But it also updates automatically to their twitter account and I view it in Twhirl as kind a rolling news ticker for stock market news. 

More importantly, Market Currents is consistent with what I think Twitter is best for, spreading links. Tim O'Reilly's feed is one of the best ways to get pointers for the most interesting articles on the web (liberal and technophile) and I find myself using it to dispense interesting posts on the web as well. Market Currents @ Seeking Alpha links out to the best of the web that is impactful on the stock market. And the realtime distribution that Twitter provides makes it actionable for stock market traders.
