On the other hand, a wiki has a community voice. Someone posts a message and, unlike with a blog, everyone can edit that post. Version control is usually present so previous versions can be retrieved and even differences between versions highlighted.
At my job, we are using blogs, and wikis for project management work; in our case web services projects. In fact, web services is being moved under public affairs in most organizations, considered more of a communication function than a technology support function.
Design reviews by client offices are done in blogs since we have superior knowledge of computer and communications systems. The design has one voice but the ability to comment by interested parties. Internally, we prepare a design using wikis. Everyone within my office has superior knowledge in different facets of a system to contribute to an overall proposal. When we have a proposed design we transfer the communication to a blog as a design review by external offices.
These approaches get buy in from both the internal staff and our external clients more so than traditional methods. The internal public experiences a more direct hand in preparing the design. The external public can see other s’ comments in parallel. Stultz (2009, p 11) says that
“But the blog rules for now. Solid relationships can be built by you and by corporations (again, you) based on honest, open dialog with superior content.”
Duncan (2005, p 392), says an important aspect of mobile marketing is that “messages can be targeted not only by individual cellular phone number but also by time and location of targeted customers.” Critical here is permission of receiver. In their article Driving Sales through Mobile Marketing, authors, Say and Southwell (2006, p262) imply that mobile direct marketing, especially text messaging can be ruinous because “the mobile phone is almost certainly the most personal electronic consumer device.” In support of this warning, another researcher Alan Chappell (2006, p1) cites a study that found 80% of cell phone users would consider ‘mobile spam’ a reason for switching carriers. Direct Marketers who fall short with mobile etiquette risk bad public relations, hardship in the mobile media, and Say and Southwell believe that ultimately it can degrade a brand (p 262).

Causal Loop P-M-S-B-D-P has an even number of negative signs so it is deviation amplifying. We would conclude the system represented by the entire Causal Map is unstable, using this strategy. It will eventually destroy itself if something is not dramatically changed.
