Feel free to ask any questions or give any comments. Feedback is greatly appreciated.
Is there a demo/preview page? It's rather hard to give you feedback without getting a feel for the product. A superficial prototype should suffice if you do not have anything functional to show. If you have a working link, or anything else that you can share with HN, please post it here and I'll try to give you some comments. Right now I am drawing blank.
We'll send you an invite code early if you'd like (after the weekend). We just want to clean it up a bit more before letting anyone in.
