... from some responders. The discussion following such posts is also 
*much* more valuable, too.  IMHO

Python.org is the political place to start; but its not much good after 
that, in regards the forking of 2.7 --> 2.8

As Ian points out, you can't expect a complete migration on the PSF 
schedule (2->3), because of the fear|panic  of a fork. So, 
comp.lang.python is the best place to find out where the Cpython 
community is, and where they expect to go (for that discussion).

I realize that many of Cpython's user-base will never read 
comp.lang.python, and then the Internet is an open field for trying to 
discern where 'they' are at, and where 'they' want to go.

What I'm trying to say is that I tap many resources (comp.lang.python is 
just one of them) and I'm going to tap that source even though I also 
tap the Internet with a google search (and others).

Eeyore doesn't like to be bugged, by double line spaces, nor by 
questions. What's the point of having a comp.lang.python news list if 
its not open for simple questions of opinion?  Yes, I know google is my 
friend.   Comp.lang.python should be my friend too.
