You're raising multiple points, but I'll try to get at a couple of them before my attention span flitters off elsewhere.

• SF was not intended to be a messageboard. Of course people have a need to converse, but the site wasn't set up to handle that. It was set up to handle sysadmin Q&A (the way votes rearrange posts nonsequentially is a big tipoff here). Using a spork as a shovel is possible but there will be a lot of complaints about its ability to do the job effectively.

• What is SU FOR if not questions pertaining to individual systems? By the definition you've given, everything computer-related could apply to sysadmin, and therefore SU has no reason to exist. There's got to be a line somewhere. Migrating questions to SU isn't some kind of punishment - it's about sending the question to the place where it should get the best answers.

• As to the glib & rude responses - DOWNVOTE!! When I get a downvote to an answer, I think long and hard about whether I'm speaking from experience or wild conjecture - about whether I've phrased my response professionally or obnoxiously, etc. At the very least, maybe you can help downvote the snarky comments right out of existence.
