Hey! Nielsen is currently in beta testing, open only to Nielsen company employees--here's what the site looks like: http://www.heynielsen.com
It's expected to go live by the end of September. The site is a collaborative work of every division of Nielsen Co, including Nielsen Media Research, Nielsen Entertainment, ACNielsen, Nielsen's business media, wireless and interactive units, and social media analytics firm Nielsen BuzzMetrics.
The company has also launched The Blog to keep everyone in the loop on the progress of the site development.
