G'day Timwi,
I wouldn't have made the claim if I didn't have enough competency in CSS to know what I'm talking about. Furthermore, I tested it before posting (albeit only in Firefox).
Aw, good on yer.
I've just tested it myself, even going so far as to use "body a { etc. }", works beaut, if'n that's what you really want. Top job.
Is anyone going to reply to the ACTUAL SUGGESTION?
Righto. It's crap, and I mean that in the nicest possible way. It's unintuitive, it breaks in some browsers (IE will "hide" the link but won't show it again), it's unnecessary, it adds an extra step for users who're just browsing through article links, and it makes Jakob Nielsen cry, tho' that last one isn't necessarily cause for objection.
Nonetheless, I commend your initiative.
Cheers,
