That's a fair summary. One of the use cases for discusslr is just to throw up a topic online and get a discussion going without needing anyone to sign up. You might want to get feedback on an idea or product for example.
Over the next few months we'll add some more features to discusslr. It's pretty basic at the moment. Next up are private conversations, better media handling and a dashboard to track user conversations and interactions. Would love to hear any ideas on improvements or features.
