Wired magazine says go to Africa and get involved with Internet related projects.
Quoting the article:
If you want to become extremely wealthy over the next five years, and you have a basic grasp of technology, here’s a no-brainer: move to Africa.
Seriously. The internet is only now arriving, and — with a billion people on the continent still mostly offline — there exists a once-in-a-lifetime opportunity to build the next Zyngas, eBays and Groupons for a huge untapped local market. You need only look at the map of huge broadband fibreoptic cablescurrently being laid on both east and west coasts, from Djibouti to Dakar, to understand how quickly and ambitiously an entire continent is being connected. It’s like being back in 1995 again, and realising there might just be a market for an online bookshop or auction website. (Want to become an internet billionaire?)
Fortunes are often made in emerging markets.
