I always felt that the two week asterisk was a useful reminder. I like the idea of some sort of automated nag.
I think that after a month of holding a trackable when you log onto geocaching.com a giant green Hypno-Signal should appear across your screen, with the scrolling words, "Place the trackable (name)... place the trackable (name)... place the trackable..."
Y'know? Just something subtle, a bit like this?

Hi,
I can't stop staring at that frog. Is this some kind of a hypnotization (LOL)!
