I know a lot. Mauku has been open for two years. Either it has not been interesting project to contribute or I have been too active myself, since no single piece of code expect mine went to production releases. I received one patch of which I included into unstable codebase. Unfortunately, the developer of that functionality never provider update of his code to fix remaining bugs.

However, I have received nice icons for Mauku (kudos to Thomas Perl of gPodder). That is the only external contribution.

Of course, the situation may be different now. If someone is really interested contributing, there should be no problem to put code into public repository.

And one important thing: Mauku (the application) is only a small part of the whole. All other parts are totally open. The most important thing is the Microfeed backend (see the relevant thread). Also, the Mauku Widget is released under GPL, and you can see the code here: http://repository.maemo.org/extras-d.../mauku-widget/ . The application is not that different.

So, there are many spots to start helping me with Mauku.
