i was asking myself if some Information Security Page is not to general for asking questions about exploit development. So what could i do or someone else to establish/build a Stackexchange Q&A Page explicit for Exploit development? Kind regards
To some extent, exploit development is covered here. However, sometimes the question steps too much into the coding techniques used that it becomes a better fit for Stackoverflow.
To be honest, I agree with you. I don't think it's unreasonable to have an SE Q&A site for exploit development. To start such site, you can go ahead and create a proposal on Area51. Explain the reasons behind your proposal and add whatever information you think is relevant.
Then try to promote your proposal. If enough people join it, SE will give you a private beta. If things go well, you'll go a public beta. If things go even better, you'll have a full SE site for that topic.
