Hi Liran:
I think this is a good start. Stack overflow has a good model that has evolved over many years that this is consistent with:
One thing that it stresses is to search for pre-existing answers to a question before asking it and highlight why the question being posed is different to those that went before, referencing other posts as required.
Why do I answer questions?
I am naturally curious and have a lot of development experience that it is clear many forum members lack.
I like a challenge and if the problem is something I have already encountered or can learn from then I am happy to jump in and contribute.
Many forum contributors are designers and not developers and so while they may have a rudimentary understanding of how to write code, many need a helping hand to address misunderstandings in how to apply code or examples they may have seen. Also one day I may need some design help
