I do use brewing software. It's good stuff. However, I also write out my recipes.
When people see my handwritten brewlog they think I have a lot of stuff in my head. But when they see the brewing software, they assume the computer does all the work.
So I say keep the recipes written down for public viewing and keep the brewing software in the same hidden nondescript security-locked file in which you hide your porn!!! Of course, that's just my $0.02
