Great article. As far as "other," social media is an interesting source of information (surprising how much LinkedIn can tell you).

Another interesting point that was raised in the comments is the filtering and dissecting of information. Questioning sources of information is, I believe, only scratching the surface of the real question: how does one identify, absorb and utilize key information. I recently had an intern working for me and one of the most challenging (and useful) parts of having him around was being forced to reassess and explain how I extracted and analyzed actionable information. Perhaps a good follow-up article to this might be tips on how to construct such a digestive framework, assuming little to no industry/analyst experience.

Thanks for taking the time to write this article.

Best,
