If all of my recipes were on there, that would be news to me. Still, it doesn't really matter to me whether I get a dollar or not for it.
What may make this hard is if we all post recipes on there, hoping to make a few dollars, who will say if they are proven and tested recipes? I don't order kits any more, but for others who do I recommend kits from places like Northern Brewer. I've brewed them, or others I know have, and even if not, they are all tested proven recipes. If I buy a kit from kitlab, and it's "Bill Mahler's IPA", and the recipe isn't actually very good, how does that work out for the consumer? Not well. I remember someone used the Brewmaster's Warehouse "brew builder" and made a recipe with 10 pounds of caramunich. No one said, "hey, dude, that won't work!" until he came to our site to question his poor efficiency. These would be the big concerns of mine- WHO designed this recipe, is it proven, and is it good?
Our site requires all recipes to be proven winners, and multiple posts will attest to certain recipes. I'm not sure I'd have confidence to order a kit from "Jake" or whoever.
