I don't like treating people like numbers. 98% isn't much and it isn't little. It's just wrong.
If I'm one of the 2% then that's everything for me. Maybe I have good reasons to be in the 2%. And maybe, not caring about that is wrong.
I would rather have a website that only works for 2% of people for the right reason, than a website that doesn't work for 2% for the wrong reason.
