I can’t say enough good things about Andrew Warner and Mixergy.
This little blog, started a couple of years ago, has now become required reading for anyone who wants to be a better entrepreneur. Way more useful than Techcrunch or anything else when it comes to helping you build your business. It has real-life stories from other people building businesses – stories about failures, tactics, and what works. You won’t find stuff this good anywhere else, even if you pay for it.
I’m a reader for life.
