Wolfram|Alpha's long-term goal is to make all systematic knowledge immediately computable and accessible to everyone. We aim to collect and curate all objective data; implement every known model, method, and algorithm; and make it possible to compute whatever can be computed about anything.

It is an IDE that automatically shares all the code you write with everyone else that is using Share, as well as keeping track of how that code is used. Allowing you to see the network that grows around code you contribute, borrow, or just happen to be interested in.
