It looks slick, but… 1. Create an account (30 secs) 2. Check my email (5 secs) 3. Press a "Click here to activate" button and be redirected (5 secs) 4. Wait for the Flash to load (5 secs) 5. Fill in my email and password (5 secs) …quite frankly, you'd have lost me at step 1 normally. The only reason I signed up was to see how many steps it took to try it. Conclusion: too many. The button on the homepage should say something like "Try now", which immediately launches the flash applet and lets me use it. When I want to save my mockup, that's when I want to enter my details.
