ubuntu-devel is open to post by ~ubuntu-developers, or moderated if
posted by others.
ubuntu-devel-discuss is open to post by anyone.

Typically ubuntu-devel is usually more technical.
Recently ubuntu developers started to discuss a lot of project wide
changes that affect all developers hence the increase of discussions
on that mailing list.
