Don't hold your breath. You haven't lived until you've been facebook poked.
My colleagues enjoy facebook because it empowers them with stalker-like abilities. That's why I continually post updates detailing mundane stuff I may or may not be doing. Oh sure, I could be working on that cure for cancer or my draft treaty that would ensure world peace and prosperity, but fuck that. Facebook becons.
The first week is the best part of facebook. After that it slows to a dull, E-xistance of everyone you know, together online for no apparent reason. It will wear off.
