Organizing your friends into friend lists on Facebook will help you keep your work friend separate from your gym friends, separate from people you met online, separate from whatever other friends you have. Friends can be added into friend lists any way you want, they don't have to even be for real groups.
If you want to separate your friends by social groups, you can. If you want to separate your friends by the how often you chat with them, you can. If you want to separate your friends by where you met them, you can. If you want to separate them by the kind of car they drive, you can.
Here's how you go about creating friend lists:
From your Facebook page, hold your mouse over the link that says "Friends" in the top blue bar on the Facebook page. You'll see a menu pop down, from that menu click on "All Friends". This will open a page with all your friends on it.
