The three vote options on Area 51 are too similar. The text on the options ends with the same word, and there are no colors defining them before you vote.
I just realized that I have been voting on, 'not a good example' instead of 'of topic example' because I assumed the order of the options wrong, and there were no obvious visual cues to tell me that I was assuming incorrectly.
I propose that you change the options to:
- On Topic
- Off Topic
- Bad Example
Those three are clearly different. I would also suggest some color cues or images to help differentiate the options.
