With this new communication tool, I feel that now, the individual can make a difference. When you have a good idea for a business or a just cause, you can share this idea on your blog with the people in your network and as they propagate your idea through word of mouth, you may find enough people with similar interest that may help you in your endevours.
More heads are better than one. If you would like to share an idea for a cause like urban farming, join a group, tweet, link up with people on facebook and Linkedin. You'll find that many people are willing to give advice and help out even if they don't know you. Likewise, you may come across someone who needs your expertise in some advice and you could help them too.
It is a great concept, making the world smaller and allowing people from diverse background share their ideas, which may allow sometime simple and good to become GREAT!
I hope to educate more people in using social media as it has enriched my life much.
