When these kinds of articles come about, I never understand the big deal. The release of the iPhone 5 doesn't suddenly make my iPhone 4s a useless piece of junk. I can continue using it until it dies and I need to replace it. Similarly, if you're doing SL work, your stuff isn't going to suddenly stop working. Your current copy of VS won't magically stop compiling SL code. Continue to use SL if it works for you. SL seemed to only have mild success as an intranet technology, so my suggestion above is valid. This problem doesn't go away with open source, since projects can die and non-backwards compatible versions can be released. No one is forcing you to convert all your Python 2 code to Python 3
