Wrote a small web app, would love feedback

I would love to see a "How it works" section on the landing page. I know there's a "Sample" section, but that just lists an entry after it was created. I'd like to see how the entry was created using the app.

Also, have you looked at this app: http://www.everytrail.com/iphone.php

The site design is nice, although the use of hash-urls for things like the login URL is mildly irritating... especially if it doesn't work with Chrome autofill.

Showing the workflow is key. I'm a RunKeeper user; do I use this on my phone like RK, or need to enter routes? Can I choose common routes that other users have put in?

I'm not a rider, but I like the elevation map in the example. Nice feature.
