Social Networks – Facebook Lists vs Google Circle
If you are like me you will dabble and activate your social network site accounts to stay current with the latest in social media, you probably have the standard accounts, facebook, google, myspace, foursquare, yelp, and various others.
The common argument we hear with why Google+ is better than Facebook is because it offers circles. Will the response is that Facebook offers Lists. Which are basically the same thing. Except they way it is presented/displayed.

Here’s what facebook posts on their site:
What are friend lists, and how do I create them?
Friend lists are a way to organize your friends on Facebook and create custom privacy settings. You can also use them to filter the stories you see in News Feed.
To create and edit friend lists, follow these steps:
Go to the Friends page. Click the Account drop-down at the top of any page, and then click on “Edit Friends.”
Click “Create a List” at the top of the page to create a new list. You can also select an existing list on the left side of the page and enter friends’ names to add them.
If you have more than two friend lists, you can also add or remove friends from lists using the menu that appears next to each name on the Friends page.

What does Google say about Google Circle:
Google+ Circles helps you organize everyone according to your real-life social.

What differs is the implementation. I live the circles concept and the ability to drag and drop profiles or assign a profile to a circle. Great way to do this. If Facebook is smart they would implement the same sort if mechanism quickly.
And really get their act together on deals, group social shopping or they will start to see a decline in core users and time being spend on the site.
Like MySpace which also had millions and millions of users they saw how fast users gravitated to another system.
