Do people know about GitS?

I follow other anime subreddits, and GitS is NOT TALKED ABOUT.

No one ever mentions its existence, they make trivia lists and it's not among their hated ones.

This is very strange to me, it's been in my top 3 since I discovered it almost 20 years ago.

Could it be that anime fans are generally younger, and this anime is too adult for them to like?
