How To Buzz Free Wifi

After I learn some new stuffs and see how the people out there they use the new social media to do  buzz marketing, communities. government so and so. Some of them really creative but some still using a very traditional way like email saja! But doesn't matter new or old they still can do it very well and spread the message. I have see how they use the Twitter to twit and make the box open and claim your prizes or use a very simple way sms only and speak out your voices!
Just want to share some idea and show you how the people now use social media to create some buzz for their event.
