If you're concerned about it, you could do a user search
on yourself, sort by reputation, and then compare your
higest-rated nodes with your lowest-rated nodes, which
might let you pick out a trend of which kinds of nodes
get voted up and which don't. It may not just be about
content, but also clarity and tone, in some cases,
though solid content will tend to salvage poor tone,
at least somewhat. I looked through some of your
lowest-rated nodes, though, and most of them didn't
seem too bad to me. (There was one that was pretty
much content-free, something about ignoring a previous
node; that sort of thing is best put in an update to
the same node, IMO. But that's just one node; nearly
all of us have one or two bloopers like that.)
I wouldn't worry too much about minor negative nodes.
The way the voting system works, as best I understand
it, it takes more than ten -5 nodes to negate the
impact on your XP of a single +50 node. Besides,
XP have no materiel value.
