I am still working out how to tune, and understanding what the different engines do, but hey I’ve been doing this for 2 months!

So if I were having to undertake MySQL troubleshooting I am sure I would find them very useful.
However we only use MySQL for small drupal and wordpress sites, for which I have never needed to perform any tuning or troubleshooting.
The most complicated thing I have done in MySQL is set up replication, and I did find that a lot easier than setting up Oracle Data Guard.

Put another way, if I create a pt-awr tool for Percona Toolkit, do you care?

I created a presentation (which I have given at UKOUG, OUG Harmony, Kscope and NZOUG), “MySQL: the least an Oracle DBA needs to know”, in which I show my fellow Oracle DBAs, through live demos, how good it is.

I have created the following introductory guide to MySQL for Oracle DBAs:
