Recently a presentation from Google about Google Reader was leaked.There’s a treasure trove of information about Google Reader, their plans, features, and behavior that they have seen. This observation caught my eye in this post from Google Blogoscoped:

2/3 of the content has only one subscriber. Think about feeds for own-name-searches, own blogs and blog comments. There are feeds with up to tens of millions of subscribers. The crawl rate of feeds is prioritized when they’ve got more subscribers. They’re updated within one hour when there’s more than one subscriber, or else once in three hours.

I can’t say I have a theory to explain this. Maybe two-thirds of all blogs are only read by the author? Not sure what it means, but it’s interesting
