I was looking for @marklit (Mark Litwintschik / https://tech.marksblogg.com) in the list as he's a geospatial-focussed blogger I've seen regularly on HN with interesting blog posts where he finds and presents open source datasets I'd never thought about, walks through some basic processing/querying steps, and provides some examples of what can be produced with the data. Many of the blog posts have left me thinking about possibilities to setup bots for uploading maps to Wikimedia Commons (for embedding within Wikipedias etc) based on these interesting datasets, or at least automating via scripts the development/upload of maps on a country-by-country basis (or other criteria) for static once-off datasets.

Unfortunately he doesn't show in the top 100. Also unfortunately, there is no blogger described in the top 100 as having a geospatial interest/focus.
