I _hate_ people using "M$" un-ironically. It wasn't funny 10 years ago when it started and it's still not funny today. How can you take that one comment seriously with that "M$" part in it.
Also, irony means suggesting the opposite. I don't know why anyone would use M$ ironically.
Judge the comment on the merits of the data provided and opinion based on that and don't get hung up on a name?
"M$" may also be useful as an indicator of bias but again, it is not the whole comment.
