New Ajax based HomePage - need some feedbacks!

Hi guys,
Please take a few minutes to review a new site I started:
http://www.pagejax.com

It's an Ajax based homepage site.
The plan is to put a revenue sharing ad section on the bottom so all folks benefit from using it.

Any feedbacks?
Any ideas of how to promote it?

 

It doesn't seem to offer anything new over the existing ones, so I can't see it catching on.

 

Thanks!
Could you kindly share an idea of stuff that can help it catch on?
I didn't see rev sharing on the others for example...

 

Nice clean layout. Therevenue sharing idea is novel. I think you need a 'call to action' to entice users to sign up - this is a very saturated market and you need to stand out from the crowd

 

Thanks Modeca!
