Installation literally takes no time at all. If you can use a plugin and their site you’re golden.
I highly recommend it so far and will continue to mess with it more. Looking forward to the coming soon ability to tweak the css to better fit the site however, its not bad out of the box (unlike so many other technically impressive services). Anyways just came across it for the first time the other day and after looking into the still private beta more the past week its only been available the past 3 weeks. Despite this, its already been implemented by over a hundred site’s in less than a month. Clearly they’re doing something right .
