[What do you want to say here? Summarize it in one sentence. The following paragraph has too many ideas. It makes readers confused on which point the author tries to emphasize] The effectiveness of communication can be affected by the richness of the information carried by the communication medium [\cite{Daft1984}]. However, current media for computer mediated communication are often limited in the amount of information it can carry. As stated by the media dependency theory [\cite{Ball-Rokeach1985}], media have various cognitive, affective, and behavioral effects. Although there are many communication means, different type of medium has its distinctive advantages and weaknesses.

[What’s the thesis statement of this paragraph? Remember, one paragraph one idea. This paragraph has two-three ideas, making it confusing to read] Food is a rich medium, although its meaning can depend on individual interpretation. Not only can different culinary tastes emphasize differences between social groups but they can also inspire strong emotions, such as happiness, affection and disgust. [\cite{Happel2012}]
