As the person who started the original thread, I'll add my 2 cents worth -

The thread involved the discussion and comparison of the program on multiple airlines. Thus, posting in an individual airline seemed inappropriate. Also, since it did involve travel with frequent flier programs, placing it in a travelbuzz category was not fitting. (That is specifically for non-ffp travel)

The purpose of the programs is to earn flee flights for flying - the core purpose of any frequent flier program. Whether or not 'miles' are awarded is to me unimportant. (Southwest does not award "miles", yet its FFP is a valid topic of discussion.)
