It's not ready yet. The seems to be a lot to be desired from this. it has potential but right now, it needs lots of work.

for instance the autosave cut you off while typing in content. Placement of content blocks is fixed Colors and text are limited with text being fixed in size. Now way to pick heading size. this may work for absolute newbies, but most users are web developers looking for tools to add to their tool kit. Posting a road map would give us an idea where this may go. Feels like a rushed product launch....
