OK, I thought a bit about @LordVapor's question. Well, at least the question made me think about doing another post, like figuring out the recipes that can be made using the top 25/100/200 flavors. I thought about what it would take to do a proper analysis key on the top flavors.
And I don't think it's going to happen, for a couple reasons.
The first is that I honestly don't think it would provide much information beyond what is already available. If you go into the flavor list and click on Recipes, the flavors will sort by the number of recipes that use each flavor. One can see that Bavarian Cream (TPA) is used in 153,000 recipes. And so on, and on... It's pretty easy to see that these frequently-used flavors are worth having in one's stash.
The second, more important reason is that analyzing the top flavors would require a lot of automated programming that would break numerous site rules. I won't go into the details, but I really don't think that @daath would like what I would have to do to get the base info.
So... A lot of work, limited results, and breaking numerous sites rules... I don't think it will happen. Sorry.
