The dude now has more of his sibling working for google than his own facebook #awkward

The G in Google is really Big!

article:
In what may make for awkward family get-togethers, Mark Zuckerberg‘s sister, Arielle, is now a Google employee.

The younger Zuckerberg is presumably making the move as part of Google’s acquisition of Wildfire Interactive, which was announced on Tuesday. Arielle’s blog lists her occupation as junior product manager for the social media marketing firm. Arielle previously offered constructive criticism of her brother’s company’s site overhaul last fall.

Arielle’s not the only Zuckerberg sibling in the business. Randi Zuckerberg, former director of marketing for Facebook, left the company last August to pursue other projects. Randi is an executive producer for Silicon Valley, a Bravo reality TV show that is raising hackles in the Valley for bringing Hollywood voyeurism to tech.

Zuckerberg also has another sister, Donna, who was born in 1987.
