I am going to open a Knowledge Community Service concerning about Contest in Korea, And I think Stack Overflow is a good example to succeed in hard circumstances. So I have been developing a knowledge service in Korean for making many first starters to specialists about programming. I guess Stack Overflow is a late starter around many original knowledge services. But It took the first place in Java, Objective-C and many other mobile language communities. So I am very eager to know how you did it.
I wonder I can ask you few questions below.
How could you make this enormous specialist interest in here.?
Which is more important for success, looking for specialist in advance or secure general user?
What things were useful for advertising your site?
Did you have a lot of information about knowledge when you first started? How did you gather the information?
How many years does it take to settle down like this?
How much does the H/W Infra cost for managing the current size of your company?
