This is really weird.
I have been getting really pissed off lately with the amount of junk I keep getting from Facebook and Myspace etc much of which comprises of pointless notifications from the dubious applications that people have installed. Facebook have apparently stopped apps from forwarding themselves to everyone in your address book automatically virus style, but regardless the crap flood is relentless.
Just as I was pondering this unwelcome phenomenon I saw this on Boing Boing: http://www.boingboing.net/2007/08/22/bacn_spreads_around_.html
It's not Spam, but it's not welcome, it's BACN!
I wonder if the term will catch on.
