Which is mostly due to lack of education. If you don't ever spent time learning, but just coding, you don't know better. And sometimes it's all too easy to get thrapped into it due to deadlines and whatnot. A former collegue of mine, unfortunately, was the best example: programmed for like 15 years years and still wrote like it was all 'C with classes' (not that there ever was such a thing). You know, writing declarations at the top of functions etc. Missing out on C++11 is just as bad.
