People love to share content they think others will find useful or make themselves look cool and smart, but are often lazy and busy, making it hard for them to share. To overcome this, you need to make sharing easy by providing a simple link that your readers can click on to send an email or tweet with the desired content pre-written. This technique involves adding a "mailto:" link to your emails and using a URL encoder to create a pre-formatted message that can be easily shared with others.
