This comment doesn't expand the conversation, it just expresses an opinion and doesn't attempt to engage the original poster. In scolding delsarto for creating a post with (I assume) limited on-topic discussion & engagement potential, you've created another post with limited on-topic discussion & engagement potential.

We already have some language in the guidelines on how to engage in discussion, but maybe something specific to "what about posts you don't think add to the discussion"? OTOH, Communities that try to enforce rules too stringently end up being communities about those rules.
