Our thumbnail scraper does not execute JavaScript. Previously, Twitter's site would partially load without JavaScript, but it would not have any of the tweet content, tweet author's avatar, etc. This is why we do not have author icons for tweet posts. It is fixable by executing JavaScript, but it's not important.
Yesterday, they presumably updated their site so that their logo was present even without executing JavaScript, hence why the scraper started picking up the big, blue bird.
We have stopped scraping for thumbnails on Twitter links, so the bird is dead. Old posts linking to Twitter will still have their thumbnails.
I know, this was about the most inconsequential update post I've ever made.
See more of our changelogs at /c/changelogs. (all changes to our main codebase get posted there, however some processes such as listing updating and thumbnail scraping takes place outside of the main application and therefore are not generally posted at this time)
I get the distaste for Twitter (I don't like it either), but I would hope most pedes here aren't actually rattled by the sight of the bird. If you are, harden the fuck up!
