I share Dr. Bonds concern. Recently (in the last 3 months) this forum started to degenerate in my opinion. Several factors contributed to this:

1. Frequent posters seeking basic information that they easily get from the card issuers website
2. Constant bickering
3. Repeated questions that equate to "what is the best credit card in the whole wide world?"

There are a zillion cash back cards from banks, credit unions, etc. If the thread is not tied back to travel, then why is it on FlyerTalk at all?

A more interesting topic would be cash back vs. points. That is at least related to travel. However, it would essentially amount to calculating the value of your travel related rewards card and comparing to the value of the cash card.
