This is a brand new social bookmarking service with some cool features you've never seen in other similar sites.
They also share 50% of their Google AdSense revenue from ads shown on your profile and other pages that belong to you.

They are still testing a lot of things, so it won't be 100% perfect if you join right now. But you can 'get in early', so to speak.
