Thanks to a new Twitter resource, it’s now possible to show support for your favorite cause without saying a word or spending a dollar. You don’t even have to send a single tweet. Twibbon is a free service that alters your Twitter avatar to demonstrate your cause for something. Want to show your followers that you’re a diehard Brazil fan during the World Cup? There’s a Twibbon for that. Want to let everyone know that you support breast cancer research? There’s even a miniature pink Twibbon for that. If you’re the one drumming up support for a new cause, Twibbon is great because it gives you an easy and free platform through which to spread the word. The best part about Twibbon is that there’s no need to edit your avatar and re-upload it to the Twitter website — Twibbon does all the work for you.
