Although I think more voting (up and *down*) would be a good thing, I don't think it should be done to make SF "warmer" and more welcoming.

I think one reason for low voting is that professional sysadmins usually don't have time and money to do everything, so we prioritize quickly and harshly.  When people see a question that's not bad enough to downvote, but not clear or complete enough to answer, they probably move on or maybe leave a comment asking for more information.  

This makes the bar for "good" questions quite high: questions have to be on-topic, *and* they have to be clearly expressed and have something interesting about them to get someone to upvote.  Looking at some of your questions, I think there are two main reasons they might not be getting upvotes:

- More obscure topics (like Notes, also HP-UX or VMS) are going to get less interest.  Your question about disconnecting users from files on your NAS box might fall into that category.

- I'm not sure how to express this, but there's something about your questions that makes them seem unclear to me.  There's lots of information in them (in one case I think the question is simply too long), but for me, at least, it's hard to figure out exactly what's being asked, what you've tried, what supporting information you have.  I can see most of that information is in the question, but it doesn't jump out at me.
