Facebook founder and billionaire CEO Mark Zuckerberg's sister Arielle is reportedly working at Google. This news caused a lot of chatter among the technorati, including buzz about whether or not a collaboration between the two Internet giants is in the works.

Arielle, Zuckerberg's younger sister states in the "about" section of her blog that she is a junior product manager for Wildfire Interactives, a social media marketing firm Google purchased on Tuesday. As such, she is now an employee of Google, according to MSNBC.

The online response thus far has mostly been in regards to the concept that the competition between her brother's social media empire and her new overlord is going to be "awkward" when Zuckerberg's sisters -- he also has an older sister named Randi who worked for Facebook from 2005 until last year and now works as a producer for "Silicon Valley," a reality TV show on Bravo -- and Mark sit down to Thanksgiving dinner.

But there's another interesting storyline that some have hinted at -- perhaps ironically or in jest -- since the purchase of Wildfire has made Zuckerberg's sister Arielle a Googler.

Arielle Zuckerberg is a lowly junior product manager at Wildfire, which seems to cast a pallor over the possibility of a collaboration coming about because of her new paycheck-writer.

But Arielle, despite being Mark Zuckerberg's sister, has taken to the Web in the past to criticize big bro's changes to the social networking behemoth, which does not bode well for any collaborations that could be considered.

And Google has been trying to cut out some of Facebook's market-share in social media, pushing its relatively-new social networking site Google+ hard over recent months. So though a collaboration could have benefits for both companies, it seems unlikely that Zuckerberg's sister being behind enemy lines will do much to make that sort of thing happen. But nerds can dream.

On Tuesday, Mark and Arielle Zuckerberg's sister Randi tweeted about Arielle's new bosses:

"Congrats @wildfireapp @victoria_ransom & the whole Wildfire team on the Google acquisition! A great outcome for a great team. Many congrats!," she wrote, then followed it up with another tweet: "Congrats Wildfire! There are officially now more Zuckerberg family members working for Google than Facebook! #awkward ;)"

The reference to at least a second Google employee bearing the Zuckerberg moniker does not appear to have been explained further, so techies are left to wonder: is Zuckerberg's sister Arielle just the tip of the Facebook-bucking Zuckerberg mold?
