Hmm... spade, eh? I guess you could call it that, but you just contributed to the problem...

I'm not a big fan of this click-zooming in a web-browsing context; it seems too disruptive of the whole screen in case of accidental interaction, and not useful enough for intentional interaction. I'd prefer simply enlarging links (by less than 20px, but that's details), as can be done now with CSS, but with smarter handling for the case where two enlarged links overlap. (It should go with the pseudo-geometrically closer one, not go the "later" one. Pseudo- indicates the possibility to weight things; e.g. if you click on the overlap of a tiny link and a huge link, odds are you meant the tiny link; you'd have clicked away from everything else if aiming for the huge one.)
