Google has been hoping to get more market share in China, but surely not this way. A tipster sends in this photo of bus ads in Xi'an, China, advertising "Googirls" with the search engine's familiar candy-colored design. Is this another Marissa Mayer project? Suggest a caption in the comments. The best one will become the new headline. Wednesday's winner: "The first rule of Hair club is you do not talk about Hair Club," by FlakJack.

Google VP Marissa Mayer likes cupcakes, we learned in Julian Guthrie's profile of her for San Francisco magazine. Mayer likes them so much that the Google exec once created a spreadsheet to maintain a detailed record of the ingredients that go into her favorites. Mayer is not, however, in the cupcake business, she corrects KQED's Michael Krasny in this clip. She's in the cake-sculpting business, thank you very much. Krasny was likely alluding to Mayer's investment in San Francisco art-bakery I Dream of Cake. Mayer, dubbed "Googirl" by San Francisco, is really into frosting: "Vanilla fudge is my favorite. It gives you brain euphoria," she told the magazine.

After Marissa Mayer announced Google Health on Google's blog, Capital Valley blogger Andrew Feinberg linked to the post in a reponse titled "Google Health is Frightening." Per usual, a link to Feinberg's post appeared in the trackbacks under Mayer's post. For a time. But soon Feinberg noticed his trackback disappeared. In fact, all the trackback links were gone. Feinberg told a CNET reporter, who in turn asked Google PR what happened. Soon the links were back. Now Feinberg wonders if Mayer nixed the trackbacks due to his critical commentary. We're skeptical. The more likely culprit? A link to Cade Metz's story in The Register headlined "'Googirl' unloads on Google Health: A seminal moment." Just like Feinberg's story, Metz's story links to Google's post. But unlike Feinberg's, it's still not to be found in the trackbacks.

Google's cupcake princess, Marissa Mayer, it must be said, runs the part of the company that actually matters: the search engine. She recently made a huge adjustment to search results to favor recent content. So I'm sure it took her about 150 milliseconds to realize, from wherever she happened to be sitting or standing at TED this afternoon, that creeps Googling for "googirl" would for a very long time find San Francisco magazine's profile of her in the top slot, thanks to a link from us that outranks the Urban Dictionary. Which is why it's gone now. You know, the worst part of this job isn't the cheap shots from sad-assed journalists who wish they could post this stuff. It's knowing that we'll never, ever, ever get invited to the Four Seasons for cupcakes now. (Photo from Mel's Kitchen)

115,000 copies of San Francisco magazine, on newsstands throughout the city, name Marissa Mayer as Google's "Googirl."

I tried not to go there, really I did: San Francisco magazine's profile of Google cupcake princess Marissa Mayer is titled "Googirl". I'm guessing they didn't actually Google "googirl" before publishing. But if Marissa really is Google's googirl? You go, girl.

The only shocker in Julian Guthrie's profile of Marissa Mayer for San Francisco magazine: That the "gorgeously geeky Googler" is well-respected within the Googleplex. Perhaps among the executives Google PR trotted out for the ritual encomiums, but not among the rank and file. One engineering group so loathed Mayer that they threw a party when they were assigned a new boss. A ray of hope for anyone still suffering under Mayer's lash: In this piece, she announces that she may leave the company in two years. If, on the other hand, you can't get enough of Mayer, here's some obsessive biographical detail exerpted from "Googirl," as well as the article's opening shot:
