A couple years back I was sent a beta invite for FROONT but didn't take it up. The email has sat in my inbox, unread, for quite some time.
Decided to bite the bullet a few weeks back and use FROONT to create http://visitmy.website and WOW, it's really, really great. The UI is one of the best I've come across for front-end design, and features allow you to create rich, responsive websites in no time at all. With a couple of projects in their infancy at the moment, I'll be taking to FROONT as soon as it's dev time.
@kaz@rrhoover I used divshot while it was still in infancy so I can't compare the two but I tried this out yesterday and the ease of use and quality of result blew my mind. I will take a look at the HTML today and see how well structured it is.
