I read the other discussions. I get that. Just looking for the practical advice- you have a lot of cards- what do you do with them? Do you rotate spending or once you have earned the points you put it in the draw for the picture to show everyone and just let it sit there?
If you're going to have lots of active cards, keep a spreadsheet (there's a thread in the CC forum, search for it and you'll find it) to keep track of them all.
You want to track: Spend requirements, due dates, balances, annual fees, and bonus rewards, to make sure it all goes smoothly. Once I've spent the required spending (for the bonus), I make sure to pay the bill and await the points. I deal with the annual fee when it's up for renewal (except for high annual fees like the Amex plat). My regular spend goes on whichever cards give me the best return for my money, in terms of which rewards I want.
