I've been wanting an easy way to gauge opinions and ideas on a topic between a small group of friends/co-workers without creating accounts on a service.
For example, I want to ask "what are your thoughts on the new logo?" and have my co-workers leave comments and upvote/downvote each other's opinions.
Ideally, like a HN/Reddit-style upvote/downvote comment system where they could just type their name in and comment/vote.
