* Maintaining a module on your own is hard

* Changing best practices, vacations, losing interest

* Proper testing of a module requires a lot of stuff from the ruby ecosystem

* Ruby ecosystem and related tools are changing too fast for a single person

* Everything has to work on multiple Ruby/Puppet versions

* Rubocop

some explanation: bastelfreak noticed in the Archlinux community that people are happy, if you send them sweets

We tried this in the Puppet community as well. Puppet Inc. received 15pounds of sweets for all their encouragement for the community.

You all keep contributing and bastelfreak will send you sweets as well!

* Vox Pupuli is the place to be if something is broken

* puppetlabs-stdlib

* puppetlabs-stdlib again

* puppetlabs-apt

* puppet-systemd (sorry)

]

???

* story time: Everytime one popular module is broken, people will join the Vox Pupuli IRC channel
* This happend twice for stdlib (we didn't break it, we just noticed it)
* bastelfreak once added a breaking change to the systemd module which killed the openstack CI pipelines (happened twice)
