Well, you may be right. However, most people like to think and give out ideas but they are unable to develop. Moreover, sometimes they do not believe that indeed their ideas are good enough.

However, mostly of the brightest ideas come from previous ideas that came up in the past. Example: fax machine..

Ideas are a dime a dozen.

Had this web site been around in 1983, my idea for a portable music device the size of a credit card having only two moving parts may have come out earlier (MP3 players).

But then I may not have been able to patent the idea or gain royalties either, since this site is for the free exchange of ideas.
