Facebook chief executive Mark Zuckerberg is scheduled to delivered the keynote address at the f8, the conference for Facebook application developers, today at 10am Pacific. Stealing back the spotlight from Twitter, which announced its advertising business model at its Chirp conference last week, Zuckerberg is expected to unveil a bunch of new features.

Kim-Mai Cutler, Dean Takahashi, and I will all be posting from the conference, but you can also watch Zuckerberg via this live video feed of the keynote.
