I gave a talk about the current state of my MapOSMatic instance on day one of the FOSSGIS 2017 conference in Passau (Germany) yesterday.
Slides with speaker notes are available for download, but as this was a German event slides are german-only.
All conference talks have been recorded, I’ll add the recording link in the comments as soon as the recordings have been made public.
