Re: [Scikit-learn-general] Dropping Python 2.6 compatibility

My own opinion, after reading the link in the original message in this thread, is to drop Python 2.6 support. Perhaps Python Weekly and LWN will report on this to increase visibility. As a follow-up, I'd like to point out http://www.snarky.ca/why-python-3-exists Dale Smith, Ph.D.

worth having is whether there are any emerging best practices in machine learning, statistics, etc. Since conferences have parallel tracks, it's possible that participants can't get to all talks of interest. Having these talks linked off the scikit-learn web page would be quite va
