I started this blog quite unspectacularly four years ago on this exact day. The real motivation behind starting this blog was that I wanted to do something (anything!) with the web space I purchased over a year ago in 2009. I had egotistically purchased the domain davetang.org1 because it was on my list-of-things-to-do-in-life2. But that was it; I had no plans on what to do with it.
