Data point for anyone who might be interested.
Just applied for my third card using wiki link and was approved. All three signature, all three approved without calling in -- #1 in June, #2 in Sept -- #1 and #2 are still open. Used cards for $1,000 spend and a few times after. Reduced the credit lines on both cards before I applied for next one (Thanks to the "Brugge/Hanson" method) -- Robert when are you going to start a blog?
Seattle/Cali here we come!
