@pedbikeinfo That initial tweet led to
1. a global database of street space changes with entries from over 1,500 cities,
2. multiple new and rekindled collaborations with brilliant people around the world,
3. some very cool papers (by me and others), and
4. a new job
The work's not done, but it's a lot different from those early days, before the birdsite got enshittified. Still fun though!
