- When I look at your site, I don't know what it does. As a result, I'll just go back to Google. I gather there are some special commands (which I see from clicking through the manage link, but when I do my first look and search, I don't know what any of them are. I would have a summarized version of :ls on your front page
- On that note, ls is a geek term. People here will recognize it, but "normal" people won't. Maybe replace with something more friendly like :commands
- I'm still not sure what makes your service different and special - why is it better than things like Yubnub? I'm not even 100% sure what I can do with it: maybe have some examples on the front page, with the command and what it will do for me. I know you're going for a Google-esque aesthetic, but they have huge recognition and do one thing only. You have no recognition, and do many things - hence tell me how to do some of them so that I get hooked.
- What the hell are all these icons up top in the search results? I've never seen most of them, and don't know what clicking them will do.
- Some of your Back behaviour is busted. Click on the first link on http://fefoo.com/help/commands.html about how big the earth is, and when the results have loaded, click your Back button. Why is the result window white?
- Your documentation is intimidating. There's much too much of it being thrown at me at once and with little organization, and the writing is somewhat awkward. You need someone who's a good writer to redo and edit most of your copy, and you need to do some thinking about ways to reduce the mental load on someone reading it for the first time.
