Fix mailing lists

[techtonik]

Mailman lists is a fine machinery powering all official python.org conversations and core development. But I heard opinion that students find them really really strange.

• - research ages of people who prefer conversations in mailing lists
• - find out what young people without habits prefer for group communication
• - find out the problems with lists that diminish onboarding experience (issue Improve pydotorg onboarding #1)

Two issues with Mailman that are affecting me personally:

• - no search - you always need to use external tools
• - no ability to read the list from the web and follow (reply) to selected threads only

​Ach no!  I always seem to do this on pypy-dev.  Thanks for pointing that
out.​

This message missed my inbox, and I didn't notice that until I needed to paste reference to it few days later.

Yes, Gratipay can be added to "the list" - re my previous message about
Flattr, in which Martin mentioned also, Patreon.  (Sorry I don't know how to
link to another email thread.  Oh, I'll link to the archive....

Collected the above in just 3 days from my own scope. Just think about how many people stumble upon this hourly. Need #30 ASAP.
