How do we grow the Server Fault and Super User communities?
This discussion illustrated some of the issues. Here are my thoughts on SF's problems:
There aren't enough experienced admins contributing. I don't think SF has reached a critical mass yet.
There's a need for some meta about SF, but meta.stackoverflow isn't working well for it. There aren't many of the higher-rep SF'ers here, and I don't think they're likely to come here. I think most people who are active on SF like the way the site works so meta about details of how the sites operate isn't very interesting and doesn't draw admins over here.
When you ask a question, one of the hints on the side is: "We prefer questions that can be answered, not just discussed." That just doesn't work well for a lot of issues sysadmins deal with. While it's certainly up to Joel/Jeff to decide what sort of site they want, I think if you rule out discussion questions, it makes it less interesting. I'd like SF to be a place where I could go (and I can suggest other people go) to get answers to all sorts of sysadmin questions, not just ones that have clear-cut, step-by-step answers.
I haven't thought about this one much, but it might help if there were a way to quickly filter the 0 votes/0 answers/minimal views questions. I think a lot of these are the "barely sysadmin" questions that people want to ignore.
EDIT: Fine, this question duplicates some of the content of that other question, but it's hardly an exact duplicate. The "problems" with SF that might be limiting its popularity with sysadmins are unlikely to be the same as with SU,
If anything, closing this supports my point #2 that a separate discussion of how SF could be made more vibrant makes sense.
