Backstory: I decided to crowdsource static site generator recommendations, so the following are actual real world suggested-to-me results. I then took those and sorted them by language/server and, just for a decent relative metric, their Github Watcher count. If you want a heap of other projects (including other languages like Haskell and Python) Nanoc has the mother of all site generator lists. If you recommend another one, by all means add a comment.

1. Get your Twitter archive;
2. Save this script as an executable in the root folder of your tweets archive;
3. Execute the script from anywhere (e.g. a cron job).

It auto-installs grailbird_updater in an isolated location. Thanks, @DeMarko!
