Business idea - Recreate whatwas before the recent template changes.

Saw this post on Reddit where most of the old users are really upset with the changes.Recreate the old Playground and most would probably switch to your site. 

Of course Playground probably had a reason to make the switch. Not big enough market, to expensive to gain users, too much compute etc. 

But from an outsiders perspective, making a flexible powerful tool that is well designed could do well.
