1. What is that domain name? What am I missing? It tells me nothing and will not help your site grown in anyway.
2. Show me, right on the front page, what you mean. I know what a slide show is, SHOW ME what your app does. This isn't that hard, but I want to see it more than read it. Give me an image of a browser window with the next content to the right and the last to the left. I like pictures.
3. Get rid of the word "test" all over your home page. Seriously, it should not be there. Put some real content (even if it's just testing content!) in there so I don't see how young you are.
4. Man, I hate registering for things. Probably not what you want to hear, but do I have to register/login? Can't you just use a cookie to identify me and link me with my list(s) on your end? I'd love to just work as a guest of sorts - forever.
