I hate it when sites change the <A> colors, because then I have to "learn" that particular site's interface rather than using the one I already know for 100s of other sites. I can understand sometimes, like you are putting text over a blue background. (But does it HAVE to be blue?) What I can't understand is when people change them to be the same as normal text until you mouseover. Users don't want to wave their mouse over the screen to see what's clickable. Please put some more thought into this.
