*Semantic voting*. You should be able to easily select a section/paragraph of a post/comment, 
and vote on it specifically. Instead of voting/liking a complete post 
(which probably contains things you agree with as well as things you disagree with), 
you can select a word/sentence, and express your agreement. 
Downvoting a word could be used to point out grammatical errors, which leads to


<p>A part of this paragraph is <span class=”highlighted” data-highlightValue=”0.1”>highlighted text</span>, as you can see.</p>

<p>No part of this paragraph is highlighted text, as you can see.</p>

//pseudo code
function setHighlight(selection){
  int highlightIterationValue = weighted percentage of all votes;
  if selection does not have class highlighted{
    selection gets <span> tags with class "highlighted" and attribute "data-highlightValue highlightIterationValue";
    add to highlightedArray;
  } else {
    value = data-highlightValue;
    value += highlightIterationValue if not higher than one;
    data-highlightValue = value;
  }

  for all highlightedArray{
    background color = highlightColor;
    highlightColorSaturation = highlightColorSaturation * data-highlightValue;
    push back to DOM;
  }
}

//pseudo css
span.highlighted{
  background color = highlightColor //if javascript disabled, all highlighted text is fully saturated
}
