Implementing a social or an e-commerce site requires skill if you don't want to deliver a me-too product that will utterly fail.
To be an entrepreneur regardless of the domain, you either have to have enough money to buy top talent or you need to be able to do the job yourself.
E.g. you will utterly fail to start a business that produces tasty eco-sausages if you have no idea how to: a) produce or buy eco meat or other ingredients and b) make tasty sausages or c) hire a chef working for a 4 starts restaurant that loves to make sausages
If you don't believe me, try it out.
Entrepreneurs that think coming up with an idea is enough, and "just need a programmer" are lying to themselves. But hey, they are free to try it out.
