What is the ideal length for (Product Hunt) posts?

A few days back, I wrote a newsletter about that. (Check in comments.) 👀 – My general effort is to fit within 280 characters (regular Tweet). – Speaking about Product Hunt, I would say 100 characters can explain everything (In the future, I will say why. 🙂) – And if you are looking for a strict number of characters within the post, e.g. how Richard Branson or Steve Jobs would do it, read below in my weekly newsletter. 👇 ––––– P.S.: What is the ideal length of the post according to you?
