Is yahoo answers culture worth saving?

ALL social media is under the full control of the Chinese communist party today so it's best to just delete them all form the world

Short answer: No.

The site is a troll swamp, a disaster area.  It doesn't represent any "culture" to speak of, beyond juvenile trolling.  There's enough of that all over the Internet.

No. The site (and offline world)  has enough garbage and nonsense. Preserving the nonsense that has flooded this site in recent years isn't worth preserving. 

Thanks for showing everyone what a loser you really are by spamming this same idiocy over and over.   You seem to love proving that the best thing you can do is to kill yourself like you have been claiming you will do for the last decade.
