To be quite honest I was pleasantly surprised to see Clojure as far up on the tier two languages as it is. As well I was please to see it was second in the amount of growth. Having recently jumped into Clojure it is nice to see the market for it expanding.
Maybe I misread, but I seem to recall a chart that showed almost 7% growth from your linked-in data. Out of the 5 shown in the bar chart it was the slowest growth, but I assumed that it was significant over languages not listed on that bar chart given that it was in the list of 5. If I misspoke I apologize, my intent was not to misrepresent the data. Looking back on the data, I don't see where I got that it was second as far as growth goes.
