Maybe Penguin 2.1 has affected a lot of your referers...
I also see this.

I am right though in thinking that referrers means sites outside of Google using Google's search data, right?
Like Aol.com search is just Google search results. That's a referrer?
Defining exactly what a google.com/referrer is has always been kinda vague.

What's your source of information? Anything other than raw logs is subject to interpretation. In particular, analytics programs other than GA may or may not recognize that a bare "www.google.com" (without query) is a search result, not a direct link.

Google Analytics, obviously. Anyone using raw logs probably doesn't have a very big site.
Sooo I ask again... What is Google.com/referral traffic?

Traffic that come from links on other sites!

"Not all referrals from Google.com domains come through organic search or AdWords ad listings. Referrals may come from a variety of sources, including Google Groups posts, base.google.com listings, or static pages on related Google sites. Such visits are tagged as [referral] instead of [organic] or [cpc]."
