so we have colors for links and non-links (text) ... but i don't think we've defined color for visited links. so visited links are same color as text. also, i think this was in the original design, not an effect of aden's recent style sheet changes.
i think it's somewhat useful that
1) a person knows what links you clicked and which you have not.
2) a link, after visited, still stands out from text
we might want to consider using one more color or contrast value for visited links. maybe adding some subtle difference might be good?
