They are a bit less than allrecipes.com

7M uniques: http://www.quantcast.com/allrecipes.com

I would estimate G+ getting 5M uniques. However, what would be interesting is to know the pageviews.

Facebook recently said they had recieved 500M visitors in a single day.

I don't think pageviews per visit is anywhere near what it is in Facebook - probably even by an order of magnitude. That is just my own perception from using it, though.

Facebook really do know how to suck time out of their users.
