1) I have no idea what this is. It appears to be a short blog post with a comment box. Don't WordPress and Tumblr serve that purpose? You need to solve a pain point, that the other apps dont.<p>2) I have to log in to comment? Wtf<p>3) If you want to start a social app, start reading how others got launched. Social apps need a "seed community". Twitter had the SF tech scene. Facebook had Harvard. The seed community gives the app its first users and helps dictate the features and tone.<p>Hope this helps. There is tons of opportunities for new online communications software. But you need to solve a unique pain and have a realistic strategy to getting an initial user base. Posting on HN doesn't do shit.<p>my 2 cents
