I'm using Twibbon for the first time. I was inspired to use a twibbon on Twitter and Facebook through the 170 Million Americans campaign to "save public broadcasting". I personally like this because I have recently decided to maintain one profile photo across social networks that looks relatively current and the twibbons let me switch things up without too much change and with supporting a cause online.
On long drives, I always search for the local NPR station. PBS can't help but be intriguing. Show your support for public broadcasting; learn why and how at http://www.170millionamericans.org/. Like PBS and 170 Million on Facebook. Follow @PBS and @170million on Twitter and #savepublicbroadcasting.
