As Atoosa Rubinstein noted yesterday, everyone's favorite ex-viral video sensation scored herself a lucrative marketing deal. LonelyGirl15 has entered into an agreement with Neutrogena — over the next few episodes of the YouTube series, a Neutrogena-employed "mad scientist" will appear as a supporting character.

At least this pay-for-YouTube-play is transparent, unlike, say, Amanda "Rocketboomer" Congdon, whose shilling for Dupont was discovered in March, to which the the ABCNews.com contributor played the "I'm not a journalist — I'm a blogger" defense card.

No one bought it.
