if you want people to write, you need to let them express themselves as they normally speak, within reasonable limits. OK, I was just, I wonder etc are all polite verbal tics that ordinary people use to attract the listener's attention.
Wonder / wander, loose / lose are all commonly mixed up. Previous generations would have written like, I say, excuse me etc.
I expect there are quite a few people on AB with mutliple identities, but this is what underemployment and simple technology has done to our society.
