Tell me which sentences you don’t understand. Start with the subject line, which, yes, misses the word “of” before “questions.” Yes, the word “about”–doesn’t match “regarding”–but it was a lapse because “asked” and “answered” really should be handled differently, but the whole “asked-and-answered” is considered (roughly here) as one set, and I would not let that slide in formal composition.
The first poster asked this, which allowed the usual slow readers to pile on and have fun:
“Are you asking if questions and answers in thread games are revealing more personal information than they used to?..”
Asked: See the large type sentence with the question mark. It announce the query, and the rest of the OP. Even if there is not a single query mark in the rest of the post. I’m sorry if the missing “of” tripped you up.
“Are you concerned, intrigued, or delighted by this change?”
Answered: Did you read or understand the last sentence of OP?
