Host reading group retrospective after 2018 cycle concludes

[dcwalk]

We've indicated we want to have a chat after this cycle ends, with a view to set ourselves up for success next time. Things we'll likely cover:

• What worked, what didn't?
• New topics/themes/futures/questions (see #31)
• How we want to manage/coordinate (see #24)
• A future schedule
• Coordination labour

We held the retrospective and have the seeds of beginning to plan the next iteration here: https://docs.google.com/document/d/1OCjnmQYA-YE0FmpagnLf3qA1IEeNz9fuIoYUONw7CUg/edit#
