> Twitter is using your app graph to help build a more tailored experience for you on Twitter.

The more we can prove to advertisers we deliver targetted content, the more they will pay us.

> Improved “who to follow” suggestions that share similar interests

> Adding Tweets, accounts, or other content to your timeline that we think you'll find especially interesting

See first item.

> Showing you more relevant promoted content.
