I usually hit new posts - but it is so common for me to have more than one YT window open - think I've got 4 open right now - lol. One for the New Posts, One for  something, I'm researching, One for a popular thread that keeps getting updates - I just hit refresh & one opened to general discussion - so I see the latest too.
 
YT overload 
 
 
Just found this thread on page 10 after going thru all the new posts - eek
