All good points, except the last...

Does anybody use PyPy, Jython or IronPython for a production web service? I'm seriously wondering. I've had the misfortune of having had to use Jython, but just to read Python pickles from a Java service (don't ask). Even that simple use case wasn't fun (the last stable release was also over a year ago).

PyPy looks great for small or new projects, but there is this disclaimer: "PyPy has alpha/beta-level support for the CPython C API, however, as of 2.1 release this feature is not yet complete. Many libraries will require a bit of effort to work..." - this has caused PyPy to be incompatible with every large Python project I've ever worked on.

And well, personal (dis)taste in .NET aside, IronPython hasn't had a release in over a year either...

Where are these projects being used in production?

Quora runs on PyPy:

Nope, not any more: http://www.quora.com/PyPy/Is-Quora-still-running-on-PyPy (The answer you linked is quite old)

I'm even more skeptical now that I see a company tried moving to PyPy, and actually hired a core PyPy developer (Alex Gaynor - http://pypy.org/people.html) to make the move, and it still didn't work out.

Yes, PyPy is used in production by many companies.

disqus, i guess!

I can't find any current information about Disqus using PyPY. Do you have a link you can provide?

What I did find is current Disqus adventures in Go due to Python not being performant enough:
