Facebook Ads Now Refreshing

Did you think you saw the Facebook ads on the right hand side suddenly change while viewing your News Feed without refreshing? Your eyes aren’t deceiving you!

This is an apparent attempt by Facebook to squeeze in more ads, particularly for users who just sit on their News Feed all day without navigating to other pages. There doesn’t appear to be a set amount of time before refreshing, but it seems to happen after a minute or a few minutes.

I haven’t seen it happen while viewing Lists or application views, only while viewing News Feed. Have you seen this yet? What do you think?
