Tangentially related to another meta post, the last discussion about this was a while back, so it may be time to revisit this topic.

The #1 answer in the chat was money, so that and fried chicken aside, how can we draw more professional system administrators to the site?

Personally, I came on board frequently last year after running into brick walls with SCCM. Even though most of my SCCM questions went unanswered, I saw that I could help others w/ their sccm problems, and got help w/ group policy and other things, so it was a valid tradeoff.
