Each of these menu items serve a very important purpose of its own – “about” tells you a lot of things about Facebook as a whole. “Developers” is the place to go if you are a developer trying to create a Facebook application. “Jobs” lets you review available positions at Facebook and apply for them (apart from letting you get lost in the world of puzzles, but you have to visit that page to know more about that). “Advertisers” is for advertisers (really?), and “polls” is the tool you need to create your own poll and get the whole world answer it. “Terms” is for terms and conditions of using Facebook, “privacy” is a note on data privacy and how Facebook handles the same, and “help” is exactly what it says – including a very useful Frequently Asked Questions list.
