Freewrite about Interface Culture

Steven Johnson, author of Interface Culture, states that the hypertext link is the first new form of punctuation in centuries. To me, and again this could be because of a lack of knowledge of written English, punctuation has a lot in common with grammar in that there are proper and improper uses of punctuation. However, because the hypertext link "lives" through the internet, it is difficult to understand exactly what would be correct grammar in its usage. Punctuation is also used to convey subtle tone in language as well as background information about the sentence or statement. In this sense, a hypertext link can offer background on whatever a person may be speaking about by linking to a page containing these previous ideas.
