I think PremEx and others summed it up very well.
Remember: Sharing is caring.
Guess I am in the camp who does not like the "secret list."
May I add another suggestion: for those of us who can't read Flyertalk 24-7 if you find a great deal --
CALL OR E-MAIL A FRIEND!!! That way you can spread the joy of a good deal. And to make it better - once you deal a tip pass it on to another Friend!
For example:
*I would have ended up like Trojan Horse over the W Times Square $25 a night deal. Someone e-mailed me the Link and details. i was able to sign up before the deal vanished.
*Another good buddy left me a message about the PVD airfare deal. Too bad I didn't get the message in time!
Here's another piece of advice == CHECK YOUR CELL PHONE AND E-MAIL EARLY AND OFTEN!!!
Good discussion here.
