Tip of the day is the start of a question you can ask chatbots:
"Here's my shopping list. Can you regroup it so items that are close together in Trader Joe's end up in the same groups..."
(Don't forget to check the list 'cos it might add chocolate just because it's learnt people like that...)

As I've said numerous times: lawyers, journalists, politicians, few of these people have any clue what numbers are and what they represent. Especially numbers bigger than about 3. They're just a thing you put in sentences to give the impression of authority.

Huge news on Patreon! Because of the Apple v. Epic ruling, they are not only dropping the 30% Apple Store charge on the iOS app, they are also halting the move to subscription billing for all creators - which would have affected creators like me, who use a "per video" structure than monthly.
