If Mozilla/Netscape increase their "market share", that will be a bad day for people involved in web production - yes, IE does not follow standards like Mozilla does, but its still better to have 90%:10% where you can just ignore Mozilla than 70:30 when you have to do things with 2 browsers in mind - who can render html quite differently...
