2. Bleep, bleep, bleep.' What's going on? Is this a lesson on profanity? No - that right there is the sound of censorship, or the suppression of information. Censorship can take many forms, from burning books to restricting what information is available on the Internet for the citizens of an entire country. At its most basic, it's all about the control of information. Whoever owns the access to information can decide what people learn and what they do not. This can be governments, private companies, mass media - any group that in some way controls access to information. But why? Well, a government or a private company may not want people finding out too much about their policies because the result could be a rebellion. Knowledge can be power. But can censorship be a good thing, too? Well, let's take a look, and then you can decide for yourself. We promise not to censor you.

Through social presence, users experience a feeling of inhabiting a shared space with one or more others, and their awareness of mediation by technology recedes into the background [22]. Social presence requires participants to experience themselves as co-located and mutually aware of, responsive to, and responsible to one another [23]. As suggested by Casanueva and Blake [24], the sense of social presence consists of the belief that the other people in the virtual environment are real and really present and that the user and the others are part of a group and process.
