How do you vote up or down on RallyPoint?

So while reading the discussion linked below, I saw that people were wondering why certain comments were voted down/up. &nbsp;That got me thinking as to why people on here decide to vote they way they do on these forums. &nbsp;While I look at social media and forums like this as a place to share to ideas and expand my knowledge; it's interesting to see what discussions get a lot of Up Votes and others that get Down Votes.&nbsp;<div><br></div><div>Do you base your decision on if you agree/disagree with what the person is posting? &nbsp;Does it have to do with your feelings toward the subject matter? &nbsp;Are you more willing to vote a discussion up if it appears to be helpful to the general public here on RP? &nbsp;Do you vote something down if you think the discussion is pointless? &nbsp;If you vote something down, do you feel the need to share why? &nbsp;Would you share if asked to?</div><div class="pta-link-card"><div class="pta-link-card-picture"><img src="https://www.rallypoint.com/assets/fb_share_logo.png"></div><div class="pta-link-card-content"><div class="pta-link-card-title"><a target="_blank" href="https://www.rallypoint.com/questions/26679-new-tattoo-policy">New tattoo policy</a></div><div class="pta-link-card-description">While briefing some young leaders about the direction the Army is going with tattoo's, an NCO yells out that's why I'm going to fully tattoo both arms in hopes to be grandfathered in.
