Ripple documentation required

[pakcoy]

Hi,

Can someone point me to a site with good ripple documentation? I need to understand how ripple works and how it can be used to make more local exchanges in a decentralized manner.
My background is programming (C++, Java), understanding of pub key crypto, etc., and Bitcoin.

Some of my questions:
* What exactly is Ripple? Why are so many people talking about it?
* How does a ripple transaction work? Is there a public blockchain, etc? Who keeps track of tx?
* How anonymous, irreversible and decentralized is it, compared to Bitcoin?
* What are a few use-cases of Ripple?
