Under all the things that show up on the Everyone's News Feed, may I suggest adding a 'like' link or button? Kind of like how we have it now next to peoples posts. I find Im on the Everyone's News Feed more than the forum and as im scanning down the feed, I'd like to 'like' some things down the line (and maybe a comment box too? lol)
I think the idea is you can like other actions too then though, like status changes and profile pic updates, location changes etc... I would like to see a ajax "Read more" option on the news feed were you can load the rest of just that post inline and if you need to read more THEN you can open the whole thread.
