Fine, I'll bite. And I'll disagree, at least in part.
The Ritz Carlton card appears to be something of a niche product and one that, besides, I don't know much about, and so I'll defer to you on that one.
But several other more-or-less greatest cards pushed on the blog really have been just exactly that -- the greatest. Specifically, the current Chase reserve card is unquestionably the greatest thing going right now, 100,000 point sign-up bonus and all. Before that, the "old" version of the Citi Prestige was clearly the greatest thing going, especially with Admirals Club access and what amounted to a 5% or so rebate on AA flights (more for me). And then still before that there was the Citi Exec, with $200 refunded the first year, Admirals Club membership and a 100,000 mile sign-up bonus.
Here's the weirdest thing, though. The blog has also pushed the Citi double cashback card. It, too, is pretty great, at least for people like me. (I have the card.) I suspect that it also pays the blogs either nothing or close to it.
So I think your point is certainly partly valid. I just think you just take it too far. WAY too far.
(Full disclosure: the new Chase reserve card, great though it may be, isn't something I'm planning to get even though I easily could; I have, or have had, all the other cards positively mentioned above.)
