Data Intelligence, Business Analytics
I think social media is a good choice, you can join the related groups and post the questions you want to know, many experts will answer you friendly.
Search and skim, refine search and skim, refine search and skim, etc.
When I search for info, I most often find that I don't know what I don't know. I start my search with what I do know, skim through a bunch of info, then refine the search or take it in a new direction and keep repeating this process until I get comfortable with my learning.
With sooooo much info available, there is info you can trust and info you cannot trust. How do you know the difference? At first, you don't. But as you read more and more and get a better picture in mind, you can start making some evaluations of the info fairly quickly. One of the searches I typically do is for PDF files and PPT files on my topic, and filter it for info created in the past 3 or 6 or 12 months. I usually get white papers and presentations made at conferences - typically pretty trustworthy.
It takes a lot of time, but just think - what would we be doing without the Internet??
