Spam Volume Falls to 2007 Levels (web.hbr.org)

Bravo!

I wonder what the reduction in infrastructure costs is to deal with filtering out that spam.

Unfortunately my spam folder remains bloated.

I wonder if the spam toolkits are incorporating heuristics to target the messages better, so they don't have to send as many.

I think social network spamming has become much more popular, I wonder if this also has had an effect as people leave traditional email spam (or don't worry about replacing it when governments shut them down).
