I get your point, and I think it gets to the heart of the matter.
Now that everyone uses Facebook, Gmail, Amazon, Twitter on a daily basis, the average person thinks of those as simple 'websites', that are easy to build.
Almost daily I have friends/family come to me with a business idea that starts off as "it will be easy.. just like <huge site> but with blah".
Non-tech people honestly think 'websites' are simple things, and we should be able to knock-out a Facebook or Twitter clone in a few days.
