The grammarsphere is the cyberworld of web pages, blogs, and Facebook groups where
English-language nerds hang out and have
raging debates about things
like "singular they", "verbing nouns", "the Oxford comma" and "logical punctuation".
"Do you want to do something this weekend?"
"No, I can't. I'm going to
meet my grammarsphere friends this weekend."
"What? You are going to
meet _who_?"
"Whom."
"The people that your meeting this weekend."
"I think you
mean 'The people whom you're meeting this weekend.'"
"I'm not meeting anybody this weekend."
"Exactly. Well, at least not my grammarsphere friends."
