And I am not talking about liking things on Facebook. A Facebook like doesn't help anyone to spread his or her ideas. It is just someone saying "hey I like your stuff". But that's already about it. I am talking about really sharing it on different social media channels by clicking the share, tweet, pin or +1 button.
This will really help your friend's ideas to reach more and more people that are located outside of his or her personal network. And that's what every small project so desperately needs. We all have to start small. All big project were once small. Facebook began small. Twitter began small. Google began small. Every successful startup out there began small. Even if you think the project is not relevant to you, share it. There are thousands of people out there that might actually like it, if they only knew about it.
So start helping your friends, click that button and help their projects to become the next big thing. Another great side effect: you will put a smile on your friend's face, for free! And always keep in mind: Only ideas that spread have the chance to win.
