Has Facebook replaced email for sharing content?

A post over at allfacebook.com points out a new report that suggests Facebook has replaced email for sharing content. Specifically:

Facebook now accounts for 24 percent of all items being shared in contrast to email which now accounts for 11.1 percent. Not surprisingly, Twitter now accounts for 10.8 percent of all items shared. I reached out to the company to find out what sampling size the company has.

Is that consistent with your experience? How do you share things online? One thing is for certain, we can’t just think about email when we’re trying to build content we want people to share.
