One of the biggest changes in the way that we interact, due to social media networks, is the sheer number of people that we can interact with.
Because of social media networks, we are now able to interact with thousands of people all over the world - this is why we see people who have thousands of Facebook friends or tens of thousands of Twitter followers. Without social media, that would be impossible. Social media networks allow us the opportunity to share opinions with a far wider audience.
Another big change that has occurred is that there is now no filter on the way we speak.
In the past, unless you spoke to people directly, you had no way to get your message across regardless of your freedom of speech. Now we can use social media to get our messages out to thousands or even millions of people uncensored.

The important part of wikis—what makes them different from any other type of website—is collaborative editing by the users. Think about that for a moment: the ability for the users of a wiki to collaboratively edit it. If you can read it, you can edit it. It seems simple at first, yet profoundly powerful in practice—and it's what both Wikipedia and WikiLeaks have in common.
