Super User - question and answer site for power users
Software gurus Joel Spolsky and Jeff Atwood released Stack Overflow last year, a site for software developers to pose questions and help each other out with answers. Since then they've been busy putting together more sites on the same engine. They now have what they are (just for fun) calling their "Stack Overflow trilogy": Stack Overflow, Server Fault, and Super User.
Since we already know what Stack Overflow is all about, let's have a quick look at Server Fault and Super User.Server Fault
Server Fault is a question and answer site for system administrators. It's the place to go if you need help with networks, servers, or managing many user's PCs. Typical topics include configuring mail servers, Active Directory, routing, and network security.Super User
Super User is, in my mind, the most interesting of the three. It's a site dedicated to computer enthusiasts, otherwise known as power users. They're the people out there that are not necessarily programmers, not necessarily network administrators, but still know how to make their computer system bend to their will, and if they don't know something, they can eventually figure it out. Super User might make the job of figuring out your next problem a little easier, since it allows you to browse a huge database of questions, and pose your own questions that other power users can answer.
Since Super User only released to the public yesterday, it's still pretty fresh and just getting going. But I suspect it serves a very large market that is hungry for a solution like this, and it will grow very quickly.
