1. Add social sharing buttons so that people who like your content/images/videos can easily and quickly share with their Twitter/Facebook/Stumbleupon (etc) followers.
This is powerful because if just a few people share, but each has a lot of fans/followers then your content is now in front of all of them! Your content could go viral and that's the easiest way to get massive website traffic!
2. Add a translator tool so that no matter what languge your visitors speak, they can read your words. Think of the millions of people worldwide who could share your content if only they could read what it says!
