This from Greg Yardley sums up my attitude too:
I’ve got no real interest in any of the crappy brands I’m given the ability to ‘endorse‘ on Facebook. You know what I want to endorse? Neat stuff. Handmade stuff. Obscure stuff. Edgy stuff. Things I think my friends will actually like, and won’t hear about on their own from a million other people. When I can click a bookmarklet or fill out a quick form and let everyone know how much I’m enjoying the monster laptop sleeve from Barry’s Farm, without forcing Barry’s Farm to pay a bajillion dollars for the privilege, then we’ll talk. And if Facebook as a company doesn’t realize that that type of recommendation – which disrupts and destroys traditional advertising, instead of trying to prop it up – is ultimately more valuable to them than whatever Coca-Cola’s paying, they’re not nearly as smart as they think they are.
