This is a pretty specialized issue; the creators of the petition only had a goal of 1,500. It was fortunate that the petition authors used thepetitionsite.com, however, as it enabled the word to spread quickly within Care2's critical mass of pet-friendly people. The tool also enables people to invite others to sign and spread the word via email. Now this woman from small-town Wisconsin has almost 2200 people from around the world standing up for her cause.
Any comments? How about other grassroots causes that have benefited in a big way from online petitions and organizing?
