There`s an interesting proposition that`s been around for at least as
long as Carl Jung`s view of the universal subconsious. It`s that an
idea is like a radio broadcast arriving on the planet as a sort
People don`t necessarily come up with an idea out of nothing; they
rather tune into this new "program" that`s beaming around the world. It
would explain why most major inventions have had many people developing
them, all at about the same time.
One person or team may come up with the first patent, or they may be
first to market, but throughout history there have been parallel
developments in all kinds of new ideas.
The whole basis of competition is like "natural selection." Whichever
is the strongest implementation, which also satisfies the largest
sector of the market will succeed.
If you and this other site both are starting up, then by all means you
should do it your way and they can do it their way. Let the market
decide which of you is offering the best product or service.
It`s almost impossible to be utterly and completely unique, with zero
competition whatsoever. No matter what you choose to do, someone else
will surely be doing it as well, probably in about the same timeframe.
What counts is that you have a passion, where they perhaps only have an
interest. We don`t know, you can`t really know, so you go out and "git
`er done!" as Larry the Cable Guy would say.
