This forum only has 97 questions so far. What is the point? It is not visited by many people. Shouldn'it be re-intergrated with the main stackoverflow forum? I find it pointless.
Welcome on Cryptography Stack Exchange!
For comparison, http://stackoverflow.com/about:
(Emphasis by me).
This site has a different topic - it is about cryptography, not about software development. While these topics sometimes overlap, they are still different. Here is the space for the more theoretical point of view.
This site was created at Area 51 - this means there were quite some people who showed interest in a separate cryptography site.
Yes. It is new (created about a month ago), and there are not many questions yet, and not many users. We hope it will grow. It will always stay small compared to Stack Overflow, but this is not necessarily bad. We hope to get some more experts (other than Thomas) which will give high quality answers to high quality questions.
You are not obliged to come here (though we do appreciate if you do - you seem to be at least a bit knowledgeable in the field).
I'm sorry to have initiated the migration of your answers on Stack Overflow here (together with the questions) - but these questions were clearly fitting here better than Stack Overflow.
If it shows that the site will not gain enough momentum to survive on its own, this might be considered. But most questions here will be better at IT Security - Stack Exchange than at Stack Overflow, if at all. (One could say this is more of a split-off from security than from Stack Overflow.)
