Eureka ! Unfortunately, I found it !! Mine just hung too ! I was in the middle of reading a post and the page froze. My cursor was active but no links would respond and I could not close the page. The page was dead to the world. I hit F-5 to refresh the page and I was back in business. Just after I answered your post I saw a similar comment:
"Hope the site works :(" from Kabster -(I think)
It's definitely this site's issue.
(Mebbe us squatters is creatin' too much traffic for the server ??)
Just keep the F-5 key in your sights until they resolve this.
