[SciPy-User] Contributing to SciPy was Re: Least-squares fittings with bounds: why is scipy not up to the task?

I would like to extend the discussion a bit.
(I thought of dropping the half finished message and go back to my
corner but I think this might still be useful.)

Code that is not ready for Prime Time
Stata has a large library of user contributed code
matlab has the file exchange
several other statistical packages have user contributed code
collections in forums
SciPy has mailing lists, pull requests, gists, tickets and
scipy-central and open source and pypi
Pull request on github are very convenient for code that changes,
improves, fixes, existing code, or code that can be included after
For new functions or modules intended for library code, I find them
easier to try out when they are standalone.
One of the bottlenecks in including code in established packages is
the time it takes to review, refactor and test code that isn't quite
right or doesn't quite fit.
I think it would be useful to have a central location for publishing
code and get earlier feedback from users. (Currently I bookmark, for
example, gists or modules in a random package, that look interesting
and I might not find again when I need them in future.)
I'm still envious of the matlab fileexchange with a very useful
commenting system where I look more often than at scipy-central, and I
like the commenting system on stackoverflow that gives a much faster
way of evaluating several ways of doing things.
I also think Mathworks and Statacorp are very smart in supporting user
code, since (I assume) that they look at the download statistic to see
what is in high demand and might incorporate code if it's license
A community supported scipy-central !?
