Youtube gained a chat function to share videos?

I just got a new button in my youtube, a CHAT!!

Anyone else?

As what does it do, sent link to your subscribers , as I don't seem to have any friends..

Nevermind I got the ref link, to make a chat on youtube

( the original 'HHYFGHTWE#$tyryrt' name)

You can’t send link to subscribers
It’s just like Facebook chat you need to add friends to chat in private.

cool i don't have it ,hehe wy?
