Too many SE sites causes confusion
First thing, I see that Stack Overflow has been remodeled into a number of other sites like Super User, Server Fault, and a lot, lot more. I think this Stack Overflow design is excellent. The UI is awesome. But do we actually need so many sites.
For example Super User, Server Fault, Unix, AskUbuntu are not much different in the purpose they serve. They might be targeted towards a different audience, but in reality we don't have so much of a strict boundary between these. I think if we have a lesser number of sites then we can have a better overall user experience. Since the post will find the answer in just one site, and no need to think which one these is the best one to put the question. I feel that reducing the number of sites will have a positive impact on the quality of the site in terms of the content.
Second thing, I wanted to know if I can get the Stack Overflow software for hosting it internally in my private LAN.
