Facebook’s latest revamp has big implications for entertainment. At the company’s developer conference f8 today, CEO Mark Zuckerberg revealed the broader purpose of the site’s recently unveiled “ticker” feature as well as a new one called Timeline, and announced a slew of content deals that will allow users to latch on to the TV shows, movies and music that their friends are enjoying. The “open graph” media apps — which will include Hulu, Netflix, Spotify and IMDb – will allow users to launch a window from the ticker or Timeline to watch TV and movie content, or listen to songs their friends have just listened to. However, as Netflix can’t seem to catch a break lately, there are complications: The company’s embattled CEO, Reed Hastings, also took the stage at f8 to talk about the Netflix integration and pointed out that current U.S. law prevents Netflix users from connecting the service to their Facebook account. Users in all the company’s other territories have the go-ahead, though. The Netflix blog posted a plea for its U.S. customers to ask Congress to reverse a law that “creates some confusion over our ability to let U.S. members automatically share the television shows and movies they watch with their friends on Facebook.”

While Facebook edges into entertainment portal territory, some users are crying foul at the new features — many have expressed irritation at the ticker for days — and likening the redesigned site to the one it usurped in social networking: MySpace. For Zuckerberg, the changes are about connection and discovery. ”We’re going to make it so you can connect to anything you want, the way you want,” he told the conference.

Before Zuckerberg took the stage for his keynote, SNL‘s Andy Samberg rolled out his impersonation of the Facebook founder:
