If you don't know myki is Victoria's
upstart usurper of a ticketing system ~*~smartcard ticketing system~*~ where you like get this credit card thing and you're supposed to ~~tag on~~ and ~~tag off~~ every time you get on or off a train, tram, or bus.
(Actually technically you're not supposed to tag off when you get off the tram, unless your tram trip was wholly within the zone 1/2 overlap, in which case you are. METLINK'S ONLY HOBBY IN LIFE IS BEING CONFUSING ok.)
myki may sound like a "good idea" if you geek out over science fiction-y smartcard systems (understandable that was my own reaction when myki was first supposed to be introduced.............. in 2006) but if you consider that Melbourne already has an A-GRADE AMAZING TICKETING SYSTEM called METCARD it basically sucks. ( And basically there's two reasons for this: )
