If you think one outcome is more probable than its current value indicates, buy some shares to increase its price.
You can buy either by entering the amount of money you want to invest or the number of shares you want to buy.
You believe a price is too high? Sell some stock! But remember: you can only sell stocks that you already own.

Launched in July 2006, Twitter is social networking and micro-blogging site that allows users to post their latest updates. An update is limited by 140 characters and can be posted through three methods: web form, text message, or instant message. The company has been busy adding features to the product like Gmail import and search. They recently launched a new site section called “Explore” for external and third party tools that interact with Twitter and a new visualization tool called Twitter Blocks.

The service was started by Obvious Corp, who also started Odeo.

In April 2008 Twitter launched Twitter Japan in partnership with Digital Garage.
