I'm developing software with the same purpose as Stack Exchange. I'm currently in the very early alpha stages; when I'm done I plan to release it as open source, localize it in Italian and open an Italian Stack Overflow-like website for programming question.
I really love Stack Overflow and I want my software to be very similar to it, so I intentionally took a lot of inspiration from its design and features. Before considering the main developing phase over I'm planning to implement all of SO's core features, like reputation, badges, close votes, community editing, etc. (Well, not exactly identical, for example the badges and their requirements will be different)
However I don't want to take it too far and make you guys mad (especially Jeff :P). So what I'm asking here is, are you fine with how I did things so far? Did I take "too much inspiration"?
I'm very open to make changes (as long as they are not unreasonable) if that's the community's or Jeff's wish.
