Wanted to share this website:
It gives 100 examples about the use of social media for learning. Since we are all students this may be helpful. The examples include Mindmapping websites and organizers.
What I found interesting is: http://www.ning.com/
With this website you can easily make your own social media website. If you are able to get a lot of visitors, you can even generate an income. So let’s activate our gained social media knowledge and create your own social media website!
