A lot of sites out there allow their users to either vote-up or vote-down content to determine both it's quality and relevance (just like this one!). My question is which set of symbols would be more effective to complement a voting system that has 2 selectable options (as opposed to a 5-star rating system, 1-10 scale, etc.)?
downwards triangle(or an up-arrow and down-arrow, respectively)
After you choose, please explain why. Then, perhaps explain what kind of use-case would be proper for each option?
The project in question allows users to write a comment after voting on a piece of content. Their vote is tallied and their comment is posted. Their vote (and comment) does not effect the sort-order of the content nor the notoriety other than what the tally-total displays.
