I'll limit it to three because: a) Parsimony, b) Blogger is being recalcitrant b*tch at the moment and is not letting me see any more than that.
1) Econ blogosphere comment form. Way out in front -- with nearly 7,000 views thanks to links from FT Alpha, Barry Ritholtz and a bunch of people on Twitter -- was this spoof of the various personalities, trolls and anti-trolls that populate today's economic blogs. Some of the additional suggestions provided by commentators were golden.
2) Thinking of doing a PhD? My post advocating for postgraduate studies in Norway accumulated around a 1,000 views over the course of the year. It would appear that the idea of drawing a healthy salary whilst having access to great data and clean air could prove a viable alternative to crushing student debt (or miserly graduate stipends) and 80-hour work weeks. As an aside: A fairly large number of hits on this one where referrals from a single comment that I left under one of Noah Smith's blog posts. Thus is the way of the blogosphere layer cake.
3) Review - Extreme Environment (Ivo Vegter). It may not have reached the top spot, but my review of Ivo Vegter's anti-environmentalism screed was certainly the longest post of the year. Five thousand words for around
If memory serves me correctly, I have a couple posts with 500-odd views here at Stickman's... while my most widely read articles of the year were almost certainly the series I did for the Energy Collective on natural gas. So, it's been a respectable year blogging-wise for yours truly. I might get around to listing my personal favourite posts of the year later during the week.
