If by "this site" you mean FT, I respectfully disagree with you. A major function of FT is to educate us to spend our money wisely (i.e., get the maximum value for our money, usually in terms of miles and points).

I can recall very few posts here which advocate just spending money which we would otherwise not spend simpky to grab some points/miles.

If you were referring to some other site, well, that's the point of just about any site - get you to part with your hard-earned dollars/pounds/euros/etc. which you might otherwise not do.
