if women just kept to one tone of voice(a normal pleasant one, not too high), men would be much happier!
(Jokingly) Women would like it if all men knew how to say was yes dear.
Robocop managed fine with one tone of voice. You could see when he was sad or confident..
(neutral) Unfortunately misunderstandings occur in text a lot, even big ones. Anything that helps conversation to be more understandable is good in my eyes.
Fact is, you can write in that you're angry or sad. In my post about Amona I think it was quote obvious I was sad. One just has to use choose the words that represent what they are trying to convey.
(happy) I like smileys though in addition to writing. If I wanted all plain text I'd go to Usenet.
