I have those things in both feeds. Everything is in my live feed, and the ones that have a lot of comments are showing up in my news feed.
For example …
A post from Frostie the Dancing Cockatoo was made about an hour ago, and has a dozen comments and several "likes." It shows up in both feeds, sort of in the middle of the page.
Meanwhile, there's a post about health care reform from a political page that's hopping, with over a hundred comments. It's almost at the top of the news feed, well above the Frostie one. It was originally posted last night and has completely fallen off the page in the live feed [but it's still there if I load more of the feed.]
