Common wisdom in most industries is to release bad PR announcements on a Friday and good ones towards the start of the week. It's interesting how the advent of twitter communication has shifted the ML ecosystem to publishing work whenever it's ready versus trying to find an optimal weekday. Or maybe they're optimizing for the weekend hackers that will take improvements released late in the week and put them into practice on Saturdays and Sundays.
It is interesting, been thinking about that myself a bit: some random associated thoughts: NeurIPS is next week, & there was OpenAI drama news that went under the radar due to Friday rule.
