In honor of Worldwide Invest Better Day (WWIBD), we at The Motley Fool are recapping our "13 Steps to Investing Foolishly" -- steps you can follow to become a better, more Foolish investor.

In the following video, Chief Investment Officer Andy Cross explains the importance of Step #13: Make Friends and Influence Fools. This final step is about tapping into the collective brainpower of tens of thousands of fellow Fools as you journey on into the world of investing.

We all understand the power of community and connections, and chances are good that you're already a member of one of the web's many social or professional networking sites, the most popular being Facebook (META -10.56%), of course, which recently surpassed 1 billion users. Facebook is famous for more than just its gigantic user base, though. Since going public in May 2012, the company has become known as the worst IPO in history, plagued by one problem after another in a downward spiral of epic proportions.

Whether you're a fan of Facebook or not, the takeaway here is that not all communities are created equal, and at Fool.com, you'll find a thriving population of smart, informed, and helpful individuals who have already discovered that, when it comes to investing, there's no benefit (or fun) in settling for solitude. Check out the video below for a rundown on everything the Fool Community has to offer, from discussion boards to our specially-engineered CAPS database. It's all free, friendly, and Foolish, and we hope to see you there.
