Bogleheads is the definitive resource for learning about investing on the internet, period. Some of the leading academics and financial advisors are active there and will actually respond to posts written about their research. Also, I would recommend subscribing to this: http://www.capitalminded.com http://www.capitalminded.com It's a weekly email newsletter that reminds me of Matt Levine's Money Stuff but with more a Boglehead-type focus. Kind of like a weekly reminder to stay-the-course backed up with some pretty interesting references from history and academic papers. Also, don't fall into the trap of checking CNBC, Yahoo Finance, etc. every day. The reason most retail investors fail to match the performance of the same funds they invest in is because of behavioral errors and getting drawn into the emotional drama of markets.
