Another “Like and we’ll donate” effort, this time from Gillette. Personally, I’ve always refused to buy Gillette products. Since I went into puberty, realized deodorant had become a daily necessity,and then subsequently learned Gillette tested their products on animals. Disclaimer over.
Their execution seems super simple, and smart. Like and Post a comment — no “custom” functionality built via a Facebook app, or external microsite. And they didn’t worry about being OVERLY prescriptive of what you have to do or write for your Like to count.
