I'll scrolled down through the items shared by my Buzz contacts and found a series of interesting posts at the bottom of the page. I had already viewed these items, so I refreshed the stream which took me back to the top of the page.

Again, scrolling down, I noticed the same items. But again they weren't interesting enough to get my attention. I was on the third or fourth scan of my Buzz stream that it occurred to me that these items were very persistent. That's when I noticed they all had comments disabled.

Google Buzz Team was the author of the items. What's up guys? Not that it matters much on a slow Sunday morning, I'm just curious. What kicks these items into my stream?
