I think the stack is at loggerheads.
We have a decision to make, attract regular folks with genuine IT Security questions, or continue to attract bits and pieces of the CISSP crowd with sysadmins who've been migrated here from serverfault, and programmers who've migrated from stackoverflow.
I'm not knocking the site, it's a good resource and I'm finding the opportunity to answer some of these questions helps me dig deeper into knowledge areas I'm already adept with. Unfortunately in order to get out of beta I think the site is going to have to become friendlier to engineers. If not users, these individuals can get us closer to going live, and I think it's perfectly acceptable (if we maintain a strict tagging policy) to gain more of that audience.
To be honest, I've started popping around on Serverfault, and the questions there that are asked which are security related are often downvoted and closed rather than answered well. I'd imagine if we can get more of these questions migrated here it would help answer some questions.
The big cons aren't only for CISO types, they go over strategies used by the badguys to compromise hundreds of thousands of end users. The "family IT guy" could use our expertise to help limit our adversaries resources. If we maintain strict editorial control over the questions, and make sure there aren't too many "hinky" ;) questions I think it's better for us all.
