According to Kress and van Leeuwen (2006), text and graphics are used together to form greater meaning as both these modes support each other. Therefore, i would think that the trends now are mostly the tumblelogs. This is because of the different media types such as the text, video, and pictures where bloggers would be able to convey their expressions.
Furthermore, Walsh (2006, p.31) states that, Bloggers enter a site is to obtain information and its main purpose is to provide people with numerous types of information. That is why, I would say that tumblelogs would be the trendiest is because people have different ideas and experiences they face everyday and bloggers would want to express them. Furthermore they also want to share about their experiences.
Old form of media Publishing: Papers or Traditional magazines, etc.Karp (2006) asserted that the old form of publication will not give up yet, they will find a way out to survive in the new media world. However, to support the needs of the target audience, they tried to explore the new technologies to deliver their content to the audiences. Goldberg, the president of information and media of Mcgraw Hill told Karp (2006) that their readers could access their content in different format: printed, online, television, blogs or podcasts.
New form of Media Publishing: YouTube, Online newspapers, etc.

YouTube has been a very popular site for so many years. It is one pit stop for entertainment, news and education. in YouTube everyone can watch any videos up to their interest. Currently, YouTube has been playing quite an important role in the media; you can watch TV shows, news, entertainment videos and many more. Personally, I must say that I rely much on YouTube to watch news from all over the world, for example: BBC news, HardTalk, Al Jazeera, etc. I also watch entertainment videos, like music videos or movie trailers. Especially, when I am boring and got nothing to do, YouTube always accompanied me.
But let’s talk about the disadvantages from viewing streaming videos like YouTube’s videos.
Copyright
According to Jones (2007), YouTube has been sued several times of copyright lawsuits; some users were not responsible enough and posted videos without permission. This is the reason why these days, YouTube had deleted quite many videos that have been uploaded before.
Online Newspapers
If only I have to choose, I will prefer to read online newspapers than printed newspapers. Why? Because online newspapers usually are more to the point, it is actual, fast and convenient. Some more, it is free. But that is not the only reason why I choose online newspapers than printed one.
According to Nielsen (2008) readers will prefer simple and informal writing than a very formal academic writings. Why? Because people tend to read fast, so the language used must be down to earth. If the words used were not simple, people will have to read one by one from each word to word.
