Facebook's Lexicon

Who else knows about this? I just found a blog post about it here:

"Facebook's new Lexicon feature (free Facebook membership required) graphs the popularity of terms used by Facebook members over time. For example, a search for the term "hangover" shows an unsurprising spike on January 1st. Looks like there is a recurring weekly hangover problem as well. And additional spikes for the days after St Patrick's Day and Halloween."

Supposedly, the data points result from collected information about how frequently a search term is posted in "public spaces" on facebook, like on peoples' walls.

This is the trend when I searched for my name (there's a peak around my birthday...!). Here's what happens when you search for "aiesec." I wonder what accounts for the spike in this one... it's almost exactly a month after IC in Turkey ended... hmm.

I tried to search for "bringing sexy back," but apparently the terms can only be one or two words, but you can compare terms in the same search if they're separated by a comma (this is an interesting pop culture trend). The graph also only goes back until September 2007.
