A service I just found for Twitter and those that love to invest and trade is called StockTwits. New services built around Twitter appear daily. Many would ask why use Twitter in the first place, and it appears that one answer is to think of it as a platform. Companies and individuals like StockTwits are using it as such.
Here is how they explain their service:
StockTwits is an open, community-powered investment idea and information service. You can think of it as Bloomberg for the little guy and gal. Eavesdrop on what traders and investors are talking about RIGHT NOW or contribute to the conversation and build your reputation and following as a savvy market wizard.
You can follow others, as you normally would in twitter, and follow specific stock tweets as a $ precedes the stock ticker. For example $EBAY. If you would like to post a general comment, not about a specific stock, you simple add a space and two $$ at the end of your tweet. For example Today’s market volume is extremely low, any ideas why? $$.
They also have 5 predefined streams for discussions. Take a look at StockTtwits.com if you enjoy the investing world and would love to have real time discussions as you make your millions day trading in the quiet of your own home, now you have a community to chat with in real time.
