I too am going through my list once again, I have done so periodically on old Steemit and new Hive platform.
Unfortunately I concur we do not get to know what is going on in the back office most of the time, not being coders it makes it difficult. Will try to also do a post with my three witnesses and why over the weekend hopefully.

Good. Looking forward to reading about your experience. I have read some other posts and there are people who are well informed about what witnesses do and their specific technical contributions. Maybe this initiative will serve to promote that aspect a bit more so that we all know the basics of this pillar of the platform. More visibility is needed
