I appreciate the sentiment but I don't think it is quite as simple as imploring people to focus on solving actual problems. The creative spirit isn't quite as straightforward as that nor is everyone capable of that 'Eureka!' moment.
Also many people will focus on building clones of existing websites because it will help them to improve and develop their skills.
Also, on a related note, would you say that cherry.ee is solving a real problem?
While I understand the creative spirit isn't always normal, I'd guess the OP is saying if you can't think of a real problem to solve then don't put your (valuable) energy and time into crap.
True - although this does rather increase the irony of the OP being involved as co-founder of what appears on first glance to be a daily deals website. I'm not saying it's crap but I'm not sure it's solving a 'real problem' of the type alluded to in the OP's post.
