I noticed that today @ http://help.blogger.com/bin/answer.py?answer=930

Usage Breakdown:

   * 71% of our users use IE6/Windows; clearly the majority yet a lower percentage than the web in general.
   * 6% use Mozilla Firefox; an up-and-comer, which we all use internally.
   * 3% use Safari; also widely used internally.
   * 2% use AOL

AOL users, as well as those unaccounted for here (Netscape, Opera, etc.), would be wise to use Mozilla Firefox in order to have the best possible experience using Blogger.
