Mark Zuckerberg may just have gotten this privacy thing all figured out, by buying up the four homes directly next to his!

The Silicon Valley Business Journal and San Jose Mercury News report Zuck paid "more than $30 million in total" for the four new plots on the 1400 block of Hamilton Avenue in Palo Alto.

For now, no one knows what long term plans he has for the properties, but it does seem like a defensive measure: Zuck heard of "a developer's plan to buy one of the properties next door" and cash in on its proximity to the CEO.
