Posterous - what's changed ref site visits?

Each week I look back at my posts here on dadamac's posterous  - and recently I've been noting the number of site visits week by week as well.

Suddenly - this week - something has happened. At first I jokingly put it down to beautiful Spring weather, bank holidays and people having better things to do than be online - but now I'm really starting to wonder what is going on.

Numbers have plummeted from our usual couple of thousand site visits each week down to a mere 66 between Sunday May 1st (86,726) and today - Friday May 6th (86,792)

So what's happening?

Any idea other posterous users? Has the same thing happened to you or should I take it personally ;-) People at postersous, can you shed any light on this?
