If lately it doesn't seem like your seeing as many post on your latest news/news feed, there is a reason.
I noticed this on my end and so has others and recently Facebook implemented some new changes so that it only shows
the posts from people you regularly communicate with. (How and who determines whats regular to you is beyond me)
If you wish to see all posts now like you used too, you will need to scroll all way to bottom of news feed page till you see it say edit options.
Then change setting on there to show posts from all friends.
I just changed mine and it made a big difference.
I wondered why other day it seemed like there wasn't as many chatting and posting online and now I know.
Anyways I hope this helps some of you if you're missing posts.
