(I accidentally asked multiple versions of this question at once.
This was because I got the following error message when submitting:
"Cannot read properties of undefined (reading 'currentUser')"
So I wrongly assumed the submission didn't work.

I subscribe to Import AI, Rohin Shah's Alignment newsletter (mostly via the LW/AF), ChinAI (weekly), Ruder's NLP (probably dead), Creative AI (annual), State of AI (annual), Larks (annual), miscellaneous blogs & subreddits (/r/machinelearning/, /r/mlscaling, /r/reinforcementlearning, /r/thisisthewayitwillbe/, being the main ones), and the 2 AKs on Twitter (Arxiv ~daily). If you need even more ML than that, well, you'd better set up an Arxiv RSS feed and drink from the firehose.
Super helpful, thanks for your answer!
