Nash is clearly loyal to LinkedIn, having recently built a four-foot-by-four-foot sculpture of the company’s logo using more than 10,000 Lego bricks. He has been with the recently IPOed professional network since 2007, when he joined from eBay.

LinkedIn spokesman Hani Durzy offered the following statement:

In his more than four years at LinkedIn, Adam helped build and lead great teams that developed some of our most important products. He also played an important role in helping shape our internal culture, and his championing of LinkedIn’s Hackdays inspired some of our coolest innovations. We wish him the best as he embarks on the next stage of his career.

Nash, whose last day at LinkedIn is tomorrow, is expected to join LinkedIn co-founder and executive chairman Reid Hoffman, a Greylock partner, and former LinkedIn Chief Scientist DJ Patil, who is now Greylock’s “Data Scientist in Residence.”

Nash is also an advisor at Marin Software and a mentor at 500 Startups.

Earlier this month, LinkedIn beat expectations with a profit in its first quarter as a public company.

Gilt Groupe, an e-commerce and flash sales site, is experimenting with selling items from a range of categories — on Facebook.

The New York-based company said Facebook users will be able to go to a special page on Facebook, where they can log in using their regular account information to browse items and check out.

The site will officially launch on Monday, featuring items from women’s, men’s, children’s and home.

Other retailers have dabbled in F-Commerce, which is short for Facebook Commerce. But with most experiments today, it’s not much different from shopping on the Web. Unlike how users pay for items in games or buy movies on the social network, retailers don’t have to use Facebook Credits, which would require giving Facebook a 30 percent chunk of the transaction.

A spokesperson confirmed it was not using Facebook Credits and said that the platform was built in-house.

In a release, Gilt explained that it will offer products on the Facebook page that will not be available on its regular site. For example, Gilt Man will launch its first sale with a themed event called Man About Town featuring clothing, shoes, and accessories, and Gilt Home will offer a Vera Wang Home sale that will be available first on Facebook and then later on Gilt. Gilt Children will also have exclusives from Nickelodeon’s SpongeBob SquarePants, including a 1.5-foot tall Lego model.

And Lenovo tries to grow a global business against competitors like Acer, IBM and Dell, although there is also a rural PC for farmers. So says Bill Amelio, CEO of the Chinese computer maker:

Making Lego movies–stop-motion films called “brickfilm”–which are a lot more gripping than a lot out there (but not much!):
