Two days ago based on the events on Egypt, I think about “Freedom of Speech", I found amazing Terms and condition in Blogger website that is:

“Blogger is a free service for communication, self-expression and freedom of speech but there are some boundaries for context. When you sign in, you should announce that you are agreeing with content policy."(www.blogger.com)

After that, I decided to have a comparison between this expression which I found it in many websites with the facts which I saw as a freedom of speech in cyberspace until now; but I found that these kind of freedom of speech in cyberspace is not really exist in our society and I think everybody knows that these kind of freedom is not 100 percent. One of the reasons which support my opinion is the expression of Wikipedia as a reliable source:

"Freedom of speech is the freedom to speak freely without censorship or limitation, or both. The synonymous term freedom of expression is sometimes used to indicate not only freedom of verbal speech but any act of seeking, receiving and imparting information or ideas, regardless of the medium used. In practice, the right to freedom of speech is not absolute in any country and the right is commonly subject to limitations, such as on "hate speech".
The right to freedom of speech is recognized as a human right under Article 19 of the Universal Declaration of Human Rights and recognized in international human rights law in the International Covenant on Civil and Political Rights (ICCPR). The ICCPR recognizes the right to freedom of speech as "the right to hold opinions without interference. Everyone shall have the right to freedom of expression". Furthermore freedom of speech is recognized in European, inter-American and African regional human rights law."(http://en.wikipedia.org)
