One of my favorite things to do on April 1st every year is to visit all my favorite websites and see how they attempted to fool their users. Google is one of the more mischievous, and this year they told users of Gmail that they were introducing an email system which would allow users to send emails using only hand motions.
Connecting with users on more than a business level such as this can build relationships which stretches into customer loyalty. Internet users are constantly looking to be amused, and when they are amused in abnormal places, they are usually very ready to share it with others.
Consider using common sources of amusement to draw in users.
