Facebook revealed perhaps the most prolific of changes to its popular site yesterday at a conference that all of the nerds dubbed "f8." There were panels all day to speak with the designers and programmers, and even Apple-like videos produced to walk you through the "new kind of profile" Timeline.  Add in a partnership with the buzzing Spotify music company, and well, we can imagine it was just about nerd prom over there at the Palo Alto FB offices this week. What was the point in all of this? Besides a couple hundred programmers getting laid last night, it was basically all done so that Marky Mark Z could meet his childhood idol, Snoop Dog.
