Nah, if anybody wants to do any of my recipes that's fine with me. Even Jamil Z and Tasty McDole share their recipes (and Denny Conn) and they are far better brewers than I am. Vinnie Cilurzo even helps brewers make a Pliny clone.
The cool thing is that 10 brewers could do the same exact recipe and get 10 different beers. Water chemistry, yeast strain, fermentation temperature, techniques, etc, all mean that each brewer will NOT make the same beer no matter what the recipe is.
There are only four ingredients in beer (usually), so it's pretty easy to assume that just about every combination has been done before so it's not worth keeping a secret. I've never yet had a beer that was so good that I felt like I had to have the recipe, although many brewers have given them to me. I can taste it and pretty much figure out what's in it.
