"could you please click on an ad or two"
Y'know, I feel I should be appalled and outraged by that crass remark, but instead, I can't stop grinning from ear to ear.
It reminds me of around 1994 or so, when the Web was first being polluted by advertising; even then, there was already a large number of users who were annoyed with the flashing, wiggling, tacky banners assaulting their eyeballs as they tried to seek entertainment, information or news. I distinctly recall news.admin.net-abuse.email and many of the other news.admin.net-abuse.* forums being invaded by pissed-off spammers and other Web hucksters pissing and moaning about how they wouldn't have to do what they were doing "if you people would just click on an ad every once in a while".
Also, as I recall, back then the original Web advertising revenue model was rather flawed -- straight-up pay-per-click, iirc -- and legions of pissed-off Web users were deliberately sabotaging advertisers' business model by repeatedly clicking on ads, driving up the advertisers' costs until many of them had been driven out of business. The marketing and advertising type, predictably, responded to this by whining about how those mean old users had broken their business model.
This kind of whining from Failbook's COO also kind of reminds me of one time about eight or ten years ago, when this marketing/advertising honcho from ABC TV went on the Today Show one morning, looked the whole country in the eye and told us in a flustering, indignant tone that viewers who skipped the commercials were thieves. As with Ms. Sandberg's tacky plea, I damn' near pissed my pants laughing.
