1. Search friends, or suggested names constantly. And the new layout focuses exactly on this.

2. Chat. (During chat: "do you know X Y?" -> 1, "saw person X with Z G" -> (if don't know) -> 1)

Disclosure: I usually don't use Facebook (just to connect with old friends, sometimes).

"I don't use facebook but I am sure they did their research, therefore it's perfect as it is."

Seriously? The reason why the search is on the bottom is exactly because I thought that

1. Facebook follows the push (feed/mail) paradigm and not the pull (search) paradigm 2. Search in a feed application is a form of filtering (if user testing shows that people miss it, you can still place it under the logo) 3. I do use facebook but I don't use the search because a) so far it has nnever shown me good results and b) it's not clear to me what kind of results it is supposed to show (my stuff, all of facebook...)

I didn't say "it's perfect as it is". I said there are good reasons why the Facebook team moved in that direction.

Only because you don't use search doesn't mean no one is. I said most of the people I know, use it to find people they know. If they want to see what is someone doing, they don't go trough their friend list (referrer volume), but they search directly the name (search volume). In this case the search volume is bigger than the referrer one. Find ways to make it easier for users to search.

I think Facebook employs in part some of the Google paradigms in UX.
