Interesting things and people I learn from. Blogs, videos, articles, social handles etc.
Ben's analysis of tech and market dynamics is completely off the charts. He writes weekly articles that are free and daily updates for $10/mo - both of which I recommend.
Paul Graham's essays are some of the best free education on startups out there. Good stuff happens on his twitter as well.
I especially like Tom's statistical approach to his research that make up his posts and email newsletters on startups and tech.
