At the time, Objective C topped the list. ITworld's Phil Johnson has updated Larbi’s research using GitHub data from the last 21 months, but instead of screen-scraping GitHub search results as Larbi had done, he queried the GitHub Archive for stand-alone instances of 'WTF' in the comments attached to GitHub commits to weed out cases where the string 'WTF' was legitimately used in the code. The top 3 most baffling languages for 2012/13: C++, Lua, and Scala. Objective C comes in at #16.
