I am Matt Mullenweg, co-founder of WordPress (18% of web!) and Automattic, ask me anything!
A little over 10 years ago I co-founded WordPress with Mike Little and have been working on it ever since, I hope to do it for decades to come. I also founded a company Automattic that makes WordPress.com, Gravatar, Simperium, VaultPress, Akismet... we're about 185 people now and growing rapidly. Happy to answer anything about WP, the independent web, business/startups, typing with Dvorak, pretty much anything.

Three hours later: Thank you so much everyone for the great questions, I also thought it was really cool how the WP community jumped in and answered a few of them even better than I could, it's a good example of how WordPress works. :) It was a pleasure chatting with you all, and hope to see you around the interwebs.
