My credit score is actually about the same as it was before I started applying for these credit cards (dropped by maybe 4 points overall).
Thanks for the reply DR88. From reading the Citi aadvantage thread, it seems like I have to wait 12-26 months or more to apply for another personal citi aadvantage product. I got both the citi aadvantage mastercard and visa 3 years ago using the 2 browser trick for 75,000 each and recently got the citi personal visa again 6 months ago. I think I probably have to wait at least another 6 months to apply for a citi personal credit card again.
I do have the amex mercedes benz personal platinum (forgot to list it). I actually called about applying for the amex business platinum but they told me that since I got the bonus 50,000 for the amex business gold, I wouldn't be eligible for the amex business platinum bonus until at least 1 year after I close my gold. I have the Chase United mileageplus already.
If anyone else has any suggestions, I'm all ears!
