the rate and quality of originality is the same. the rate of unoriginality and idea-grabbers is just much higher now due to the internet, technology, and spread of information. turn-key software and internet businesses are just very easy and cheap things to start.
i can't say for sure where the internet is going, as the internet is fickle, or what the next big tech will be. at least in america, we're heading into or already in an economic downturn, so innovation will be slow in coming until we're out of that. 2008 will probably be flat.
i've only really had one really good idea lately and it has to do with reinventing the wheel for a niche old, monolithic industry. that would be the startup i'm working on now. its not any revelation for the masses, but having one monetarily successful startup will allow freedom for me to innovate in other areas without having to worry about paying bills.
