I don't know exactly why some get no votes, as opposed to No Best Answer. I know that once in a great while I'll select No Best Answer, because the only person who answered the question didn't really answer it: raised another question without really shedding light, or cracking a joke, or answering a question but not the one that was actually asked. Or a one-word/one-sentence answer with no sources for something that really should have had a source.

I also don't think that people realize they get points for voting. I only see a handful of people regularly voting, and those tend to be high belt levels--which is probably one reason they ARE high belt levels.

For people reading this answer, if you're going to vote, please don't just select the first one on the list. Take the time to really read through and think about the answers. Look to see if someone really addressed the question; if they made a good effort to explain; if they included GOOD sources--anyone can throw a link out there, but does the link really back up what they say? I always give bonus consideration to good illustrations, good pics and good videos, as well as well-written/well-organized answers.

I hope that helps explain at least a little of it.

Not sure I understand what your getting at? You mean people are not voting for you answers in particular or in general. I personally vote on around 30 Undecided questions everyday, and for everyone I vote for I can see that others have been voting too.

The only time a question gets the "No Best Answer" declaration is if the person who posed the question selects that option or the majority of the voters select "No Best Answer"

Do you have any examples of your problem that I can look at?
