Sorting my friends into lists has revolutionized my experience on Facebook. If you have not started to use this relatively new feature then you really should consider doing so.
You need to access all you friends first. Go to the menu bar item on the left sidebar that says All Connections. On this page will will see a list of all of your friends and their photos. on the left side of their listing click the link there, as I have all mine in lists, my link says “lists”, yours may say something different. Mouse over create a new list and create a category for that person. I have my account set up with lists for Family, Friends, Work, and Acquaintances.
Work your way through your friends list assigning friends to one or more lists that you have created. Now, go back to your profile home page. You will see a new navigation feature under status updates with the name of your new lists. You can sort how your lists appear there by just dragging them into the order you would like.
For me, no longer do I have to wade through the wall postings and status updates of acquaintances that clutter up my home page, I can go to family and see immediately what my son or nephew is doing. Using lists is a huge time saver and as your Facebook account grows allows you to stay in control over what you see in a glance.
