Yes but if you look at the return on the effort for the founders - you cant beat it. Obviously it is not possible for everyone to set up a FB or Google but there are still opportunities online
I you dont think people will 'get it' they probably wont. The best names are the simple names that make it clear what you do - best to keep it simple, they are easier to remember. Names that don't make it clear require more marketing budget so that people get to know the brand.
Without doubt the internet. Most of the companies that you use today such as Google, Facebook, Plenty of Fish were started at home.
