FFS, 411 was amazing before the web.
Also, in about 1989 my friend and i used to have a contest between us; to call 411 and see who could keep the 411 operator on the phone the longest.
This was a fun social engineering exercise for 14 year old nerds who like the idea of being phreaks.
Our record was 45 minutes and got to know a lot about the 411 system, where call centers were located and how the 411 system worked.
This was right near the time that we ran the long distance bill up to $926 for one month of calling into a BBS in san jose and PCLink to chat....
Got grounded for a month for that one...
