There are three situations:<p>1) the idea is sufficiently novel that it would be difficult for an average person to conceive without suggestions<p>2) the idea is commonplace, but the value-add is something that is not obvious<p>3) the idea is a clone.<p>In the third case, there's really nothing you can do to protect yourself.<p>The second case is what happened to the Winklevosses. Their value-add, the idea of exclusivity, is something that a lot of people write off as obvious. However, and a poster correctly pointed out, the idea of social networking is commonplace. The cachet was an idea that the Winklevosses figured out, and that essentially was what propelled the entire project (had that been commonplace, someone else would have tried a long time ago)<p>Again, its difficult to protect nontechnical people in this circumstance, but the idea would be to let the technical people build the standard stuff first and then reveal the value-add after trust has been established (the winklevosses made the mistake of revealing the value-add way too quickly, before establishing trust)<p>In the first case, you definitely want to learn the technical stuff yourself. Especially if the idea is really good, in which case any developer would try to zuckerpunch you. You don't really have any protection, other than potentially trying to patent.
