Draft for blog post on mybinder.org repo2docker and binderhub upgrade bot

https://hackmd.io/@sAS1NBPHT6eH_oXlubd8kQ/ryp1x6qxH/edit

Is there a way to combine or edit the first two paragraphs so we start the reader of with a combo of the two (the following needs some heavy editing read it as an outline): BinderHub and repo2docker are key components of mybinder.org, we want to always run the latest of each, this means there is a repetitive task that needs doing, henchbot automates this!

Updated first paragraphs!

The post looks really great. Well done on both the post and the bot itself!

Thanks, everyone! I’ve updated the post with the feedback I’ve gotten.
