Erratum in Cereal Poll

I have overestimated my analytic capacity in my last post. I fear there are too many criteria one could use in deciding which cereal is best, and it would be impossible to include all serious contenders, past and present, in a blog-style poll. So, basically, I cannot determine which cereal is the best of all time. A study which may lead to a meaningful conclusion is which factor is most important in picking a cereal. This one should be straightforward, but again, any feedback on this inquiry is welcome.
