Paul Graham is, in short, one of the great innovators of the Internet era. Seven years after selling his company Viaweb to Yahoo! in 1998 for 455,000 shares of Yahoo! stock, Paul co-created Y Combinator to provide seed funding to startups with a bias towards tech and online ventures. Y Combinator has become the world's foremost startup accelerator and has previously invested in companies such as Dropbox, Coinbase, and Stripe. Along the way, Paul has received many accolades, including being listed in Business Week's 2008 edition of "The 25 most influential people on the Internet". But one piece of advice from Paul has always stood out to me, and that's his philosophy on domain names.
