Thanks to GDPR all users can export their twitter data in a machine readable format. I did this, converted all my tweets to activity streams RDF and put them on my Pod. Here is the result.
All tweets are grouped in containers by year and month starting from: https://angelo.veltens.org/public/tweets/
An example tweet:

In case you are interested in the code (wich is totally hacked together quickly): https://gitlab.com/snippets/1988617
Perhaps someone wants to build a cleaner solution, e.g a CLI tool to do this.
