It is has gotten really old with the steady push of CSP cards. One of the sites seems to make it almost their top "new story" every day - which is quite the turn off for me. I get the card has benefits - have had 3 of them so far and plan to get another in a 2 or 3 years as I do not qualify now due to 14 new cc accounts in the last couple of years.
It is a good card, but not great IMO. Many bloggers are obviously making good money on those who use their links. In addition to all of us who click on their site or receive their e-mails.
I am thinking most of these folks started this out as a hobby like us with nothing but good intentions - and enjoyed sharing the knowledge but unfortunately got corrupted with the referral links - turning them more into salesman because the can see how lucrative that is for them. Much like many politicians running for office on principal but later becoming company people...
