Says: Less people understand the philosophy now
Can someone please change that to Fewer people ...
Less is used with stuff; stuff can't be quantified. Like, I like this person less than that person. Because liking isn't generally quantifiable. It's not discrete.
Fewer is used with things; nice solid objects. Why does mom give me fewer pieces of candy? She must like me less than you.
Since people are generally things, not stuff, I think we have fewer. Unless someone has been chopping them up, and we have some fractional people, and it's all gotten very messy.
