Sorry, edited to actually complete my thought in the first sentence.

While I do agree, in general a lot of novel ideas get dismissed out-of-hand, a conversation about to what extent an idea engages with the existing community/literature around that idea is valuable. For example, if I saw a paper posted here that claimed it solved P!=NP, my first question would be as to how much it addressed the existing work, as mathematical ideas tend to attract cranks.
