I see lots of suggestions here for dealing with bad questions and content but I actually think as a community we already have that part figured out. Anyone who is an active participant on ServerFault can pretty quickly identify content that doesn't fit well with the site. A question or answer is bad or incorrect? Downvote it. A question or answer is off-topic? Vote to Close. The only additional thing I think we could improve upon is leaving polite comments on why a new user's question was downvoted or closed. Perhaps a set of standardized comments could be integrated into the Review UI or we could all just start using Greasemonkey.
I think that the Information Technology Professionals
scope really has the potential to turn ServerFault from a place for Operations folks to talk about Operation-y things (a good thing!) to Operations folks doing tech support (a bad thing!). Just look at the screen cap of the front page in @MDMarra's answer - we are being treated like tech support for SO. And I'm not the only one that feels this way.
a) Soft skill questions like "What kind of format works for technical resumes?", "Is it worth getting a NetApp certification for a job with the following duties?" are all off-topic on ServerFault for good reasons.
b) I don't ask questions that are highly specific to technical problems because I expect that they will get closed as either To Localized or go unanswered due to the deep-knowledge issue addressed by sysadmin1138 in the Why "professional capacity"? question. An examples of these kinds of questions would be a very ugly periodic issue with Samba's RID to UID/GID mapping that would break NTLM authentication to our Squid Proxy Server that nagged us for over a year before it was resolved upstream by the Samba team. I find that I often push these questions to either payed support or to development/technical mailing lists with good results.
c) I don't ask general systems building architecture questions because I expect them to get closed for not being specific enough (so NARQ or NC). Honestly, this is where I think ServerFault could really shine. An example of a question along these lines are, "How can I bring configuration management (along with documented change and revision control) to a Windows Server environment using tools like SCCM, PowerShell, MDT, WAIK in a manner similar to what Puppet or Chef can do for Linux?" or "How can I introduce Windows Core to our Test/Production tiers while keeping the Full Install at the Development tier without running into integration issues during applications deployment?" I think these are great examples of Good Subjective questions (see (Good Subjective vs. Bad Subjective)[http://blog.stackoverflow.com/2010/09/good-subjective-bad-subjective/]) but there's no doubt in my mind they'd be closed. Like I said, I think these kinds of systems building or architecture design Good Subjective questions really should have a home here and really could be an area where ServerFault really excels as a resource for professionals.
As someone who is only an occasional participant in ServerFault I can't say I'm really a part of the community here but even I try to get a dozen or so votes in a day. That's pretty horrible by most standards but around here unless things significantly changed since Ward's Call to Arms for voting, it's apparently not that bad:
