A diagram describing overview of diaspora for new developers

I think the wanna be developers like me face the problem of having a little or no knowledge of diaspora as a whole. So a diagram indicating what are the components and how they interconnect will be of enormous importance for them. I have prepared a diagram and included it in the wiki as a start.

It doesn't look very nice and is far far from complete. But I believe can be improved to something more valuable.

I have time to work on this. So please provide me some feedback and I will work on improving/correcting or even completely removing it.
