Snapchat also hasn't proven it can generate a single real-world dollar from end users or advertisers.

They could implement advertising, fuck the entire service up, and all the teens jump ship to the next app that allows you to easily import all your contacts.

There's no "lock in" with social networks like Snapchat. Want proof? Friendster, Myspace, etc.

The main theme I was trying to get across is that it's more realistic to build a profitable business, instead of throwing efforts towards eyeballs, vc-cash, and a lottery ticket chance of cashing out.
