It seems pretty expensive to me for information that is usually available for free. I agree that Flyertalk is a kind of fire hose of information. It is good for us travel geeks, but not necessarily for everyone. There are both free and paid options that provide simplification. I don't see any reason to go with a paid one when you can get the information for free. Note that the free (and probably some paid) sites are usually ad/referral supported, so you do need to make your own judgement on the author's intellectual integrity.

I know this first hand since I run one of these sites. My site is free and supported by ads/referrals. I will state that my site is not biased, but you shouldn't believe me (or anyone else) - you should investigate it for yourself. One easy thing to look for if a site is promoting credit card bonus offers is if the 75,000 Citibank American offers features prominently. They are great offers and I don't believe that a blogger can benefit from them. If you see someone promoting a 30k or similar Citibank AAdvantage offer instead, you know they are looking after their own wallet instead of yours. Also, trust your gut!
