A cuple more PQAs that I found interesting:

Fodor's - hotel and restaurant finder for mayor cities
ATMs-Visa - Search for ATMs of the Visa/Electron/Plus network near an address
BigCharts - Stock graphics, quotes and news
chp - Realtime California Highway Patrol Incidents....great for finding out the reason of that traffic jam.
OAG - Flight schedules and status of some airlines.
