Why and who is canceling Yahoo answers?

For the umpteenth time: Because Verizon Media is choosing to shut it down (just as they did Yahoo Messenger and Yahoo Groups). No specific explanation was given, but considering the significant decline in quality of content on the site versus the cost of cleaning it up and keeping it running, it's not a surprise (a disappointment, but not a surprise). Do you really think this question hasn’t been asked dozens of times already? One need only review the question list to find the responses.

Verizon is Cancelling Yahoo Answers 

Yahoo Answers has not been doing well Lately a lot of Users have Left Poor Maintenance of the

Site they have not Fixed a lot of the Problems they are Likely Losing Money on it as well so

They feel its Best to Close it Down If there not going to Fix it they minus as well Close it

Down

Verizon wireless bought it from yahoo. They are canceling it because they don't want to be bothered with it since it doesn't make any money.

Because this site has a declining user base and therefore declining revenue from advertisements. Verizon owns Yahoo Answers. They are the ones who are shutting it down.
