In the spirit of my previous post about the signal-to-noise ratio element of Twitter, the edgy, thought-provoking site brainz.org has “a completely unscientific (yet accurate) look at social sites” that lives up to its title.  While the article doesn’t dissect the actual content of the various popular social networks, it does provide a candid analysis of the types of people that are hanging out on sites like Myspace versus Twitter versus LinkedIn, etc.  My personal almost-spewed-diet-coke-on-my-monitor favorite is their classification for 12% of Myspace users, which I will leave for your personal perusal.

There is a litany of other “20 reasons for…” and “30 ways to…” analyses on the site in Drudge Report-style simplicity that are pretty interesting as well, including a fun walk down memory lane with “12 Dead Technology Advertisements“, which conjured up memories of the old big three online service providers: Compuserve, Prodigy and AOL.  Ahh, the good old days.
