I get the idea and I think it's clever. It might even work to convert leads. But as a user, I find it rather intrusive.

I've come by quite a few websites recently who fire this in my face prematurely. It feels rather annoying to get a "please don't leave us" pop-over when all I wanted was to move the mouse out of the way so that I could read the site's content (which is now impossible due to the aforementioned pop-over).
