I’d rather read what somebody has to say if what they have to say is worth reading - and it could be littered with spelling mistakes as far as I’m concerned.
On the flip side, diddlydo may spell correctly, but she has nothing worthwhile reading because, frankly, she’s dim.
I detest people who pick up on other people’s spelling mistakes and grammar misuse - they’re pathetic and are clearly inadequate in their real life, but I must admit I do find it mildly amusing when diddlydo does it because she herself and often gets it wrong.
