Ask HN: bad ideas vs letting creativity flow
Say you're working with other people, and you're trying to come up with cool ideas / features for a startup. Lots of ideas come up, and a good chunk of the team seems to like a particular concept, even if you think it's not that great. In fact you feel that based on all you know and your personal experience, the idea is pretty doomed to failed, but the rest of the people are really excited about.
You now have the option of either spending hours debating people about why their idea sucks (potentially coming off as the "uncreative guy" who's all about curbing people's enthusiasm / destroying ideas and not really gaining their favor by crushing their dreams) or you shut up and let them go on with it onto the development / prototyping phase, potentially wasting months and implementation on something dumb. You don't want to be the guy who's no longer invited to discussing ideas cause he'll just rip them all to shreds, and so your opinion will no longer be considered.
What's the best way of handling this? I'm all about thinking outside of the norms, challenging conventional wisdom and letting people brainstorm their... guts out, but at some point you need to really see what makes sense, as it will cost a lot of time and effort to attempt to turn that idea into reality.
