I don't mind seeing interesting ideas freed from smug people who'd rather hoard them publicly. I don't mind seeing interesting ideas freed from anybody, really; by simply stating an idea in public, you're setting it free. But I especially don't mind when it's Dustin Curtis, whose ideas are small enough to be freed so easily and whose ego is huge enough that we get such an overblown response.
(In response to your post-edit: Nobody's trolling him. They're creating a service which, it seems, many more than just 6 people want. Why is spreading a good idea considered trolling?)
