The typos in Lerner-hakase’s posts would indicate to me that he’s just jotting off answers offhand when he feels it is needed rather than that he’s laboring under an excessive burden of questioning. And as Aeronaut has pointed out they have been very informative answers 🙂

The other side of that coin would be that good manners indicates that we should appreciate the time spent on such… and we also should understand that at other times he may not wish to spare the effort.
