My wife came across an unusual post when searching Craigslist for Montessori teachers. Among the many schools listed was a post from a ticked off parent warning people about a certain school in Mesa –the school happens to advertise on Craigslist. I have not seen this kind of activism on Craigslist before, directly insulting the advertising of another even though it is nothing new to online and social media.

It brings to mind a story I heard some time back where someone was so angry at a camera retailer that he took out pay-per-click ads for certain keywords on Google so that anyone typing in the name of the retailer who ripped him off would see the ‘ads’ that warned buyers of doing business with the store.

Today I heard an example of Facebook activism on For Immediate Release. It was a case of students in the UK using the social network to mobilize and protest against HSBC, a bank that had reneged on its promise of interest-free student loans. The latest update is that HSBC gave in!
