Agreed (up to a point).

The biggest issue to my mind is that adoption by the ultimate end
users is significantly hampered by the fact that big projects like
Twisted, numpy and the like, have no current plans to move to Python
3. Even end users with a reasonable level of coding expertise don't
have the time or resources to offer much in the way of help with a
port, when the project as a whole isn't interested in starting the
process.

At the moment, it seems to me that this is the biggest blocker to
Python 3 adoption. And it's a chicken and egg situation - I don't use
Python 3, so I don't test the new features, so the projects I need see
little take-up, so I can't use them in Python 3, so I don't use Python
3...

And while I know I can run Python 2.x and Python 3.x side by side, at
the end of the day, I want to just be able to type "python" to get my
interpreter.

I don't know how to solve this (assuming that "just wait" isn't going
to do it). Maybe the core devs will have to offer resource to some of
the key projects to get things moving (but as this is a volunteer
effort, that isn't something that "just happens" either...)

Paul.
