Facebook moves into new Menlo Park home today

MENLO PARK, Calif.

The nine building property that was formerly Sun Microsystems, spans one million square feet, but that still may not be enough room to accommodate Facebook's growing workforce . They've barely moved in and CEO Mark Zuckerberg has already announced plans to expand.

More than 2,000 current Facebook employees are reporting to work at the new location today. Some residents are worried about the extra traffic.
