Try creating a thread in the Dev & Tech board, but avoid mentioning or shilling altcoins. For example, do you think that "Full-Chain Membership Proofs Development" is worthy of discussion? Fine. Create a thread and talk about it, but don't make it seem exclusive for Monero. If you're looking for a pro-Monero group to discuss with, then head towards their ANN thread. (In that case, this thread.)
This should work fine, if OP start a discussion about the technical side of the implementation and not about the coin by itself then he can get some feedback from the community about the topic.
I don't think this site is the wrong place for that discussion, here you have the right people to talk about the project, but you need to use the tool wisely to get into the topic and to bring the users' attraction to your thread.
