It is condescending to suggest to a group of people you don't know that you have a better grasp of how to use data than they do.
You used the fact that people do this on the MailOnline to justify what you said here. When the Mail is referred to here it is usually disparagingly.
What does that blog have to do with what is on this thread? Just because a woman with a MN blog uses data in a way you don't like, doesn't mean the posters on this thread are going to do the same (if it wasn't for you rushing in with your pearls of wisdom).
Maybe it's time to stop digging.
