Stack Overflow also tracks your moderating activities, and
awards you with badges at certain points. The moderation
tools become more available to you as you earn reputation.
When you earn access to these tools, remember how you were
treated, and try to raise the bar in your treatment of others.
The easiest way to improve others' experiences on the site
is to fix obvious and fixable problems with their questions.
(See the prior section on asking questions.) Again,
that gives you +2 rep for accepted edits. If you're conscientious,
you will likely have some edits rejected that should have been
accepted - just remain conscientious and continue improving
content, and you will be rewarded over the long run.
You can also participate (as you earn the privilege)
in reviewing posts. Be conscientious if you do.
If the community, a moderator,
or the system tells you you're wrong, then you're (99.9%
of the time) wrong by definition. Happily accept your
wrongness, try to learn from it,
and continue helping as you can. If you get
temporarily banned from the review queue from time to time,
take a break and come back when your ban is up.
Remember, it's all just internet points, which probably won't
be worth anything ever. Maybe something when the singularity
hits and AI takes over, but I don't see that happening any time
soon, so you have plenty of time until then. (I would think
that StackOverflow's internet points would be the most valuable,
at that point.)
