Facebook is the principal digital public square of today. And while many young people might prefer Snapchat or Instagram, Zuck & Co's social network is still an extremely integral virtual venue and will continue to be for some time.
  1. See Who's Snooping In Your Account

Want to know if someone is logged into your Facebook account without your permission? First, go to your settings page. Under the Security folder, you'll see the link "Where You're Logged In." Here you will find all your active Facebook log-ins from desktop or mobile. It will (usually) provide data on the location, browser, and device. If something seems fishy, you also have the ability to "end activity" from individual or all devices.
This also comes in handy if you logged in to your friend's computer or on some public laptop, but forgot to log out.
2. There Are Lots of Secret Emoji

Emoji. They take away some of the horrible pain of writing in plain language. Facebook will render all the usual face emoticons into pictorial representations. But there are a whole bunch you may not be using.
(y) = thumbs-up 'like' symbol
(^^^) = a great white shark
:|] = a robot
:poop: = well, you know
<(") = a penguin
3. Transfer Files Over Facebook Messenger

If you open a Facebook Messenger window, there's a little paper clip icon along the bottom. This allows you to upload and send a file directly from your computer. The receiver can just click on the included link and download them from there. Of course, never download anything from someone you don't know.
4. Create a Customizable Supersized Post

Sometimes you want to share something that is worth more than a few sentences or a single image. If you don't have your own blog you can take advantage of a Facebook "Note." This is a personal blog post that lives inside the Facebook ecosystem. Here you can share paragraphs of text and multiple images (no HTML coding knowledge required).
Just head on over to facebook.com/notes, where you'll find notes from people you follow. If you want to add your own, just click the "+ Write a Note" link in the top-right corner. Spill your thoughts using the easy post editor, add a cover image if you want, and share just like you would a regular Facebook post. If you can't finish your note in one sitting, save it and publish later.
5. Curate Your News Feed

Your News Feed is your home on Facebook. And as your home, you should try your best to keep it clean, orderly, and free of distractions. You don't want to be inundated with posts from that one brand or friend you follow who just posts all. the. time.
One of the most direct ways to do this is by giving more voice to the things you want to see, while removing the stuff you don't want. The quickest way to access this feature is by clicking the three dots next to "News Feed" at the top of the left rail. Choose "Edit Preferences" from the pop-up screen, click "Prioritize who to see first," and choose the people, Pages, and brands you want to see more or less of in your News Feed.
You can also click "Unfollow people to hide their posts" to mute annoying posters (they won't know they've been muted). This feature is also accessible by clicking the little arrow in the top-right corner of a post and selecting "Unfollow [Friend]." You'll still be "friends" but you won't see their posts on your News Feed unless you re-follow them down the line.
6. See What's Happening Right Now All Around the World

Facebook Live is an increasingly important medium (we use it quite a bit here at the ol' PCMag). One of this live platform's coolest features is an interactive live map available, which you can find at facebook.com/livemap(only available for desktop).
Here you can scroll zoom all around the map of the world and see tiny blue the current live streams and how popular they are (larger dots have more people watching). Placing your mouse over each dot will present a preview. There are a lot of local news broadcasts, televised soccer matches, and pairs of giggling teenagers. It's a strangely engrossing experience.
