Just wanted to note that while the posts were terse, I can't say I would consider them arrogant or non constructive. If I were the author of Enigma I'd be thrilled to get feedback from Filippo. Also, it seems immediately constructive just from the reply you replied to. That said, I kind of have to agree, "you don't know what you don't know" often holds true in the matter of cryptography, and failure tends to be pretty damaging to the user. Actually, not posting a disclaimer when trying to solve a difficult problem as an amateur might be what should be considered arrogant.
