I spent many years doing something similar, blogging about what I had just learned (no posing of questions, though). I posted once or twice a day in two blogs and what I learned wasn't so much via the content as it was via the research and curation skills I taught myself. To me, research is all about staying committed to the information I am looking for, yet being flexible in my approach (something I learned growing up with a computer, ie, a problem needs solving so I look at all the ways to solve it).

Still get close to 20K pageviews/month in the main blog even though I barely post anymore, which is cool, and the result is the same as your blogging and books...sharing what you learn with others.

Now I'm taking on a new subject/blog. I will try to use your method. Thanks!
