I mod IHUB's two Berkshire Hathaway boards. There's much about the Buffett and Munger approach that regular investors can apply to their own portfolios. I've studied just about everything they've written over the decades and successfully applied it to my own needs. My individual investments are all Buffett-type blue chips and bonds.
I was also a very early buyer of Vanguard's John Bogle's index funds, about 30 years ago. Bought my first stock when I was age 19, many decades ago.
Other than that, I'm mostly a long time basher of penny stocks and bad investing.
