Notes
  • The settings UI hierarchy does not correspond to the URL. For example, 1) Settings → 2) Privacy → 3) Your Twitter data → 4) Account → 5) Gender is /settings/your_twitter_data/gender and the sibling 5) Age tab is /settings/your_twitter_data/age. External links that would open a new tab are clearly marked (eg, see Legal links under /settings/about).
  • Tweets can appear in many UI contexts. Eg, both /home and /explore/tabs/:tabID have links to /:username/status/:id (ie, the URL hierarchy doesn't nest under /home and /explore, respectively). It makes sense both from a user interface / URL perspective to point to one location as every tweet is globally unique and associated with exactly one user.
  • Tweets are accessed by ID. This is nicely terse and avoids collisions. However, given that tweets are so short, their entire text contents would fit within URL limits like /niedzielski/status/hello-world. It would be interesting to experiment with this. What do you on collision, /niedzielski/status/hello-world-2? What about when a tweet is empty and just photos? Are named tweets more usable in practice or just cumbersome to share? Eg, https://twitter.com/niedzielski/status/1347422718929502210 vs https://twitter.com/niedzielski/status/exploring-a-new-art-style-for-natureelsewhere.-higher-resolution.-no-more-backpacker.-wip-sketch-screenshotsaturday-indiegamedev-httpnatureelsewhere.com. Compare to Stack Overflow.
