If you run an online store and your products are the kinds of things people wouldn’t mind sharing info about, then you really have to consider adding a little widget or button to your order confirmation page that integrates with the customer’s twitter page which tweets such information.

A classic example would be something like: “I just bought a Google Nexus One from MobiCity.com.au – http://short.url – it’s awesome!”

People like to show off a bit, esp. with gadgets and you can customise what it says and try different ones. Of course it’s totally optional but it’s handy for getting the word out to people.

Try it!
