Social computing systems such as blogs and wikis have been used quite extensively in the last two decades by technical savvy and young users to publish their journals both for job and leisure purposes. However, the latest new development was the use of weblog as the preferred platform for knowledge creation and sharing in many commercial organizations due to its popularity and ease-of-use. Most studies conducted by researchers had been focused on motivational factors aspect of blogging. However, technological characteristics of weblogs and features provided by the platform had attracted many researchers lately to study the fit between tasks performed by users and technological features offered by social networking tools such as weblogs and wikis. This paper intends to explore an additional new dimension, “task categorization” characteristics of tasks carried out by employees of companies as they do their day-to-day activities, onto the Task-Technology Fit Model discussed in, to provide a more appropriate model that explains the use of weblogs for knowledge creation and sharing which will be further tested and evaluated by selected Malaysian ICT Small-Medium Enterprise (SME) companies. The proposed model will be explained in detail its rationales and objectives to justify the need to consider and enhance the model with a new dimension. The paper will conclude with a set of proposed further research activities at the end of the paper.
