Filecoin is “live” only technically. There is no way for individuals to contribute, which seems to be intentional as the leadership is looking for corporate support first. It currently has no real use cases. I say this as someone who is also excited by the idea.
Perhaps you can clarify the relations between IPFS and FileCoin? I was under the impression that they were related projects of Protocol Labs, with IPFS being a dependency of FileCoin.
