If you have spent any time on the internet, then you probably know all about the different “wiki” floating around. Basically you take a topic or subject and then users can edit and add to the page of that topic. Now some people have given the financial sector a try.

Wikinvest allows users to edit interactive charts of different companies. For example, if Apple (APPL) recently saw a run upwards and you know why, then you can add it to the chart for everybody to see.

Be careful of believing everything you read though, as most of the comments will come from people of all sorts of investing background; nonetheless, it is always interesting to see other people’s take on things.

Other than stocks, contributors can also add ideas to different concepts such as: rising oil prices, credit crunch, or subprime.

Overall it is a pretty substantial free service, that, at the very least, gets you thinking. With already over 100,000 contributors, you know everybody will have their own view.
