You are doing a great job of telling me what the site is about, but you should also show how it actually looks/works. I see that it is a website to save/share stuff and I am not sure whether to sign up or not because I don't know what the actual inner pages are going to look like. Is it as simple as the home page etc or will it get more complicated and difficult to use? There are a lot of sites that does this same thing and why should someone sign up for this site? Some screenshots or video demo would be helpful in this case. But again, my biggest problem with the site is that I still don't understand what problem it solves.
