"This question shows research effort; it is useful and clear"
"This question does not show any research effort; it is unclear and not useful"
Those are the messages that appear when hovering over the voting-arrow buttons of a question. The issue I take with it is that the semi-colons seem to imply that display of research effort is synonymous with usefulness and clarity.
If they are not synonymous, I would like to request the feature of changing the semi-colon to a period.
