For someone who’s livlihood depends on Ideas (by choice), I find Google frustrating and fascinating as well. All possible ideas are already there, it has come down to who can enter the best search key word to find something thats all. Thats the frustrating part, the fascinating and liberating part is being able to find references to sell ideas to clients who would not get it otherwise.
Sometimes I feel like a cheat, for almost copying someone elses ideas, however, I look at the new generation, and they have no qualms about copying ideas, so I guess this proprietory feeling I have is just an old fashioned idea, which will soon be subsumed by the wider culture of open source, open lives and open societies. Jury is out though.
