Technology looks like it's the place to be, even with most of the world being in recession. We are seeing a new generation of tech millionaires which are making big bucks before the age of 30. Most millionaires generally seem to make their money after they turn 30, when they realise the fun and games are over.
If you have free time, have an idea, love your idea, have a computer and access to the internet who knows where you could end up. I'm sure many young millionaires didn't know they will get as far as they have.
Unsurprisingly, Zuckerberg topped the list but one that did surprise me was Angelo Sotira, one of the co-founders of DeviantART. I personally didn't have a clue DeviantART was that big and was making enough money to make one of its founders one of the richest young tech entrepreneurs.
