I just wonder, as a blogger, where the balance is. Now that United and Delta, soon to be joined by American no doubt, are fare-based in terms of earning mileage, I don't think anyone would argue that credit cards are the best method for big mileage balances.

If the above is true, and these blogs are all about helping people accrue the biggest mileage balance, then they should absolutely be talking about credit cards.

I think once a blogger makes the jump to offering credit cards it marks a delineation in audience from the FT crowd to the average joe out there in internet land, since most FTers would have already heard about the credit card deals out there. As a generator of content it's probably pretty tough to keep your feet in both camps.

(I don't run affiliate links on my blog, simply because I don't have the traffic yet to support it, but I 100% plan on having links if the opportunity arises)

Making any significant amount of money from the blog (if that's a goal) is almost impossible without the credit card links, is my only point. I started my blog for fun, but as it begins to take up more and more time (alongside my full-time job), I'd like to at least see a little income from it.
