Describe the bug

The "subscriptions" sidebar on /blogs links to a twitter account that is no longer maintained (last post October 2020) and to a Python-Dev mailing list archive (that ends in June 2019).

The same applies to the sidebar of the Python Insider blog on blogger:

I'm not sure what these links should be updated to or what they should be replaced with but it seems a bit misleading to endorse them so prominently when they are no longer maintained.

To Reproduce

go to https://www.python.org/blogs/ and https://blog.python.org and look at the sidebars and follow the links.

Expected behavior

Useful links for people to learn more or stay up to date (?)
