I read somewhere that the math only works out if you're riding 3+ times a day, but the 72-hour pass basically pays for itself if you're doing one longer day trip. The ferry ride alone is what sold me on those cards, honestly.

Wait, are you telling me old bookmarks still actually work? (I swear half my saved links from back then are dead by now.) The tagging thing is the real loss though. I had folders like 'php-oh-god' and 'how-to-fix-my-printer' and it was ugly but functional. Now I just hit save and pray Chrome's search finds it later, which it never does. Honestly, your post makes me want to go dig through my old Delicious exports just to relive the chaos.

Forget it, the coupons only push stuff you already waste money on.
