This is an interesting question; one which I feel for greatly, and one which we have been discussing internally. Not having this detail worked out before going public was probably a mistake of ours, particularly as now we keep getting distracted, but we are rapidly working on addressing the issue as quickly as possible. I am going to give you an answer to this but want to stress that this answer has not been vetted through anyone else and is a look behind the curtain (and I hope you can give us a little benefit of the doubt here, at least based on the track record of some of our developers).

One issue is that we have put a lot of effort into the whitepaper, and we really want people to review the concepts in the whitepaper and give us feedback on that, but I will say that it is highly likely (if not a foregone conclusion) that if we have source code available, code which we know isn't done yet as the whitepaper design has been leading ahead of the implementation in the code, that we are going to have people only downloading the code and giving us feedback on the code... but what we really need is feedback on the design, not the first draft implementation :(.

On the other side of this, our team includes someone from the Free Software Foundation who feels some strong moral pulls towards doing all of the development in the open immediately and yesterday. I have made sure that my code is ready to release on a moment's notice and still feel proud about what is out there (though there is one last super high-level thing in the organization of how the code for the network connects with code for services that I want to fix tonight, and issue that will be much easier to deal with fixing at the git level if I didn't think I'd be breaking anyone's clone).
