Unfortunately, by simply clicking "Like" on a Facebook that you want to read updates from, your Timeline can become more cluttered than ever. You might see more sponsored posts related to your Likes, and you'll be announcing each Like to all of your friends. Wouldn't it be nice to follow pages without announcing them to everyone or flooding your updates?
A poster at Lifehacker made a relatively clever suggestion for this issue, and it's super easy to still get the end results you want. Instead of clicking "Like" on a page, click the small cog icon to the right of it. Then, click Add to Interest Lists.
If you don't have any Interest Lists yet, you can click the link to add a New list. A pop-up window will appear, which walks you through setting up a new list. Interest Lists can be public, shared with friends, or private.
After you're finished creating and organizing all of your Interest Lists, you'll find them on the Timeline landing page of Facebook, at the bottom of the left-hand side menu (as shown in the top image). These lists will also appear in the mobile app versions of Facebook.
Using Interest Lists not only allows you to organize the pages you follow on Facebook, but also helps keep your Timeline a bit less cluttered.
