While I'm not "in" SV I do interact with many who do. I think SV it's more "cool" to give honest and direct feedback above anything else.

Though my observations are purely anecdotal as are yours (I'm assuming). But I don't think it's healthy to encourage if you think the app is stupid. Feel free to refrain from commenting at all but let the people who really like / use the app be the cheerleaders.
