Just today, I was at home getting an address up on yahoo search and the map I decided to use had me enter the start location to get driving directions. Since my printer no longer works (continuously spits out paper), I went to the library to get a printout. Put in the address same way as before and the starting location was already filled in. Just a coincidence, I believe!
Maybe Yahoo being too clever by half? Figuring that since you’re the only one who ever asked how to go to that place, they’d help out by supplying your remembered start address? I’d be both weirded out and annoyed.
