Awesome investing track record over decades, but more importantly, the idea of investors helping other investors plays out on the Fool's discussion boards.
Waaay better than other investing services I have had... and a ton of different services to tailor to your specific investing needs.
Tip for consumers: Ask questions and use the discussion boards; some pretty smart people there!
Products used: Numerous ones over time; currently Blast Off, Stock Advisor and Rule Breakers
