When I visit your site, a blurb of text flashes for a minute then turns into your headline/call-to-action. Also, "Continuous Integration for Web Apps" jumps to "Continuous Integration (3 extra spaces) for Web Apps" after half a second. I'm on your side but there are very obvious deficiencies in your client-side app.
Agreed. There's only so much you can do with 2 people, and we've chosen to prioritize fixes to our platform over the UI. Difficult choice, but I don't think having a 1-page app affects it except positively.
The "Continuous Integration for Web Apps" flash is due to our Kissmetrics client-side A/B testing. An interesting point is that if we were doing server side A/B testing, we probably wouldn't see that. On the other hand, once I saw that for the first time, I realized it drew my eye to it, and figured it's not a bad thing. But maybe I'm compensating.
I'm on Chrome 21.0.1180.89 on OSX Lion BTW.
