Okay I skipped three days, so here are three tweets on a big thing I did at Maps.Me. It's on the deep end of the iceberg.
In short, I was tasked with bringing subway networks to the app. Which was based on OSM data, so naturally I thought how to fix the data model: every city had its own tagging schema.
To monitor the process, I wrote the validator, which now powers @organicmaps :

Alexey later improved it, a lot. Now there are over 300 cities, all uniformly mapped!
It was made possible with planning, iterating, and preparing a detailed tagging schema that incorporated most tagging practices:

It started as a proposal, which failed the voting. Then I made another proposal, but didn't have the nerve to go through voting the 2nd time.
But also I noticed how most objections come from just a few people in EU, so I just started tidying up networks in many cities, and when we passed 80 (with help of other OSMers), it became the standard.
