Discuss: Is Facebook or Twitter the better tool for raising a ruckus online?

Sacromento radio station KRXQ has started to face the consequences for the appalling transphobic comments made on The Rob, Arnie & Dawn Show. In addition to being named Asshats of the Week, three sponsors pulled their advertising from the show: Snapple, Chipotle Mexican Grill and SONIC.

Some of that success can be credited to a Facebook group, Boycott KRXQ Sacramento, which collected contact information and posted a list of 18 sponsors of the station, making it a useful organization tool.

This isn't the first time social networking websites have played a role in fighting for gays. You'll recall the #Amazonfail controversy spread quickly thanks to Twitter. The two sites seem like a powerful combination: Twitter is great as spreading news quickly, while a Facebook group can be a place to focus on network building and resource building.

That got me wondering: Have any readers used either technology to organize for a cause? Did you retweet #Amazonfail messages? Do you turn to Facebook groups to find other people working towards a cause like boycotting KRXQ? Let us know in the comments!
