One of my first attempts at writing was a post titled the Power of the Head Wiggle after I returned from a trip to India in early 2009.  I first posted it as a note on Facebook and received favorable feedback from my friends and contacts.   After I started my blog, I soon re-posted the write-up on this blog.  It has by far been the most popular post I’ve made.  Most noticeably, it had been cited as a reference on Wikipedia under the term Head Bobble.   It has also been cited in other people’s blog post such as Mind Your Decisions.
