Many years ago I made a conscious decision to stop correcting typos and spelling mistakes in my casual semi-real-time communication. Basically chats, messaging, and social media. It was a conscious effort I made after years of being pedantic about my spelling.
Because I can type very fast correcting my spelling before sending would usually mean x3 the amount of time wasted on messaging. In fact I was so weird about it people would remark when id correct myself after the fact how they knew what iw as saying so it wasnt needed.
Since I made the choice I realize this was the smartest thing I could have done for one reason I didnt expect. I mean sure it saves me time in casual communications where formality isnt important. But it also filters out a very certain type of people, the kind who assume typos determine the value of your message. Like there are actually people who will say "he had typos/misspellings, therefore he must be the one is wrong"... its astounding but its common. I realized eliminating these people from my feed has left a much better quality crowd who are much more productive and enjoyable to interact with.
@LouisIngenthron @freemo Whether or not it is in fact faster or less error prone I have no clue, but that corollary doesn't appear to true, it was apparently designed to alternate left and right hands so the first typewriters didn't jam. The "slow typists down" thing seems to be an often repeated myth.
