What will the experience be like for my users?

From Videoegg

Our philosophy is “Nice Works” and that extends to every part of our business.

Our ad units are really two units: an invitation and an overlay.  If the user engages the invitation they will then view the overlay on your site.  We do this because it’s the nice thing to do.  Your users are enjoying your site, so there’s no reason to shuffle them off to some other site.  If they desire to learn more about the brand offer you are presenting to them., we provide them a seamless way to do so wtihin your site environment.

Our invitation units open to reveal the overlay when the user clicks or hovers over the unit for a set amount of time, and all of our units include an obvious way to close them.  Nice really does work.
