Now through May 27, when you use Gowalla on your iPhone, Android, Blackberry, Palm Pre, or iPad to discover and share places with your friends, you might win a copy of Jeremy Keith’s HTML5 for Web Designers.
How it works couldn’t be simpler. If you aren’t already a player, download Gowalla. Then, when using Gowalla to check into a location, if you find the HTML5 for Web Designers book item, just add it to your collection. On Thursday, May 27, ten random people who picked up copies of the item will be chosen to receive the actual book.
Happy hunting and good luck!
