the collaborative and information sharing features of blogs and wikis might be much more important while the formal chart and task dependency management features of more traditional project management tools might take more of a back seat.
In such processes where innovation, collaboration, learning, and mentoring take precedence over a set timelines and task dependencies, the core features of the blog might provide major benefits, especially if use of the blog can be tied to a reduction in inefficient email attachments and meetings.
There are certain types of projects where the size, complexity, and time dependency call for heavy-duty task- and resource-management tools that are well integrated with corporate management, HR, and time reporting systems. In such cases the communication and publishing functions of the blog would take precedence by making the availability of reports and data from the more structured tools more accessible.
