Not taking sides here but bloggers are not ombudsmen.

A blogger, while this term is somewhat ill-defined, isn't quite a journalist yet many bloggers write as well as some of the best journalists and perform quasi journalist-like functions. And while you wouldn't expect a journalist to represent readers in a PR meeting like this, bloggers and journalists can voice reader concerns.

Despite the fact that I have access to many of the same corporate and PR resources that the bloggers being discussed here have, I don't really spend that much time covering cards and miles and points in what I do (I've zoomed in on a few things that I've tried personally such as Amex Platinum benefits and the JP Morgan Palladium card but it's not really my beat) - so I do read some of their blogs from time to time and I find them valuable and generally well written. I also learn a lot from members here on FT for that matter.

No one can be all things to all people and expecting anyone to fulfill this expectation is going to be disappointed in certain respects.
