Of Dollars and Data stands out as one of the most intellectually rigorous personal finance blogs available. Nick Maggiulli, the author and COO of Ritholtz Wealth Management, combines data analysis with accessible writing to challenge conventional financial wisdom. His evidence-based approach to topics like dollar-cost averaging, market timing, and wealth building offers refreshing clarity in a space often dominated by opinion. The visualizations are excellent, and complex concepts are broken down without being dumbed down. While the posting frequency has decreased since his book 'Just Keep Buying' was published, the archive remains invaluable. Highly recommended for investors who appreciate nuanced, data-driven perspectives over simplistic financial advice.
