Right-clicking or swiping up from the bottom on this page will reveal 'Pin to Start', 'Favorite', and 'Link or Edit' options. If a number appears in the 'Link' button, it refers to how many profiles are currently linked to that contact (as discussed below). 'Edit' allows you to adjust and enter any additional information you have on the contact that the social network may not have provided already. Tapping 'Pin to Start' will make the contact a tile on your Start screen, while 'Favorite' will place that contact front and center in a prominent position on your main People screen.
Tips and tricks
Opening People for the first time is an underwhelming experience. None of your accounts, other than your Microsoft Account, will be synced, making People a desolate and deserted place. To rectify this, enter Settings in the Charms bar, and add some accounts. The setup isn't daunting: Just hand over your login information and passwords, and refresh the main page to enjoy synced connections.
People does a decent job of linking the same contacts from different networks under one profile, but it may miss some duplicates, or you might want to manually link two accounts together.
To link two accounts under one, click a contact and swipe up from the bottom or right-click the page. Click the Link button, and you'll see all the accounts linked to that contact on the left side. If you don't see the contact you want to link under 'Suggestions', click the Choose a contact button, locate the contact, and click Add. Once finished, click the Save button at the bottom-right corner. Both of those contacts will appear under the single name, with the contact you originally started with as the dominant one appearing in the contacts list.
Although user-interface adjustments in People are severely limited, you do have a way to "zoom out" and parse through contacts by letters of the alphabet instead of scrolling through hundreds of contact names. If your machine has a touchscreen, use a pinching motion with two fingers on the home screenthis action will activate the "semantic zoom" feature for that bird's-eye, alphabetic view. If you're using a mouse and keyboard, you can activate semantic zoom with the scrollwheel on your mouse. If you need to search for a specific contact, use the Search function in the Charms bar.
You may see a thin green strip next to a contact's profile picture. This indicates that the person is currently online, and most likely available for instant messaging. If you would like to see everyone who is online, swipe up from the bottom or right-click on People's home screen. Click the Online only button, and everyone who is offline will be filtered out of the contacts list.
