Given how people here will seemingly do anything for miles (see this credit card thread: http://www.flyertalk.com/forum/Forum.../004580.html), I was surprised at how few of us switch credit card allegiances multiple times.

As of 8 a.m. ET Jan. 19, these were the results of Randy's AirPoll:
How many times have you switched your credit card program allegiance?
Never: 38%
1-2 times: 37%
3-4 times: 16%
>4 times: 8%
