Five really good blogs we read this month: a fascinating first-person account of the days leading up to Redfin’s IPO, from none other than their CEO; venture fund FirstRound’s 30 best pieces of advice to entrepreneurs (our personal favorite: #17: Demo your product with the young, the old, and the drunk); some remarkable data on the differences in economic growth between the largest cities and smaller communities from Brookings; and a twofer from Jason Lemkin – some solid advice on how to get venture funding and an even better explanation on why one company is successful raising $25 million while another is not.
