So basically from what I can see there is no point in ever going below 32kbps as you’re gaining filesize and losing quality.

Because computer mediated communications is language (specifically, written word) dependant, it is subject to the constraints of low/high context cultural patterns <a href="#morse46">[46]</a>. As indicated earlier, the role of language is to carry meaning, and interpretation is an integral part of culture. Language is one means of establishing context among participants of a particular culture group. In low context cultures, language must be specific and well defined, to provide the contextual definition in which to interpret the communication. On the other hand, in a high context culture language may be vague, lacking the specificity of the low context culture, as the environment within which communication takes place clarifies the specific meaning of language <a href="#morse36">[36,</a> <a href="#morse41">41]</a>. Thus language plays a key role in the communication process. A key issue determining the success of computer mediated communication is the encoding/decoding by which that communication is done. Given that computer-mediated communication is a textual (electronic) rather than a visual (face-to-face) medium, meaning must be carried by the language itself rather than relying on the environmental context as the means of communication and/or interpretation. Given this relationship, because the language of communication is English, low context communication is presumed, thus perhaps disadvantaging those whose cultural background relies on high context communication.

Interestingly, low context participants concentrate on the participation environment, while high context participants concentrate on their individual work/effort and/or skills in the discussion.

Noticeably however, the responses indicate that cultural background directly influences the priority of perceived benefits received and challenges posed from the same asynchronous communication network. The perceptions are based on learning patterns which are developed as part of a participants’ ethnic/cultural development, and are potentially challenged by participation in an asynchronous communication network, which of itself is implicitly culturally based. Further, high context participants in an asynchronously delivered seminar, while assured of higher quality participation through an offline ability to infer meaning through low context communications, are at least initially more likely to be disadvantaged by technology differences as well as the communications norms implicit in their cultural background.

<p>The above example demonstrates the power of the wiki to make collaboration more inclusive and knowledge construction efficient, distributed and fast. If you think about this visually, the email/Word scenario has limited periods of creativity separated by the logistical and socially sensitive task of combining edits:</p> <p></p><div align="center"><img src="/download/attachments/54/ch1-lowproductivetime.jpg" border="0"></div><p></p> <p>The wiki completely changes this by shifting logistics to the shortest possible segment of time at the outset, leaving a much greater period of time for collaborative creativity and knowledge construction:</p> <p></p><div align="center"><img src="/download/attachments/54/ch1-highproductivetime.jpg" border="0"></div>

Professional designers should not feel threatened by this proliferation of content created by enthusiastic amateurs - the more experience people have with creating content for themselves, the more they will appreciate the skills the professionals bring to bear.
