Blast from the past. Saw a link to this today, kind of entertaining, except the Flash part. 
As a side note, anyone here use WebFlow in conjunction with or as a developer, prototyping, production, etc., ?
I see it has an Export Code feature, is the code quality really any good in most cases ? Some of these offerings are intriguing just based on the visual UI’s. But sadly code quality seems to be the downfall generally as its second fiddle and not at the forefront. There are some that have pretty nice UI’s so I understand why they are appealing to designers and frontend minded people.
Anyone have any experience with such related builders, and can attest that they actually produce quality code that fits nicely as part of production and development workflows ?
