Researchers found out that " Wikipedia is significantly more biased than Britannica by their measurement, and a bit more left-leaning." But isn't the biggest and the most important thing of Wikipedia is their neutral point of view policy? This is introduced by the Wikipedia founder as the core principle of the community in our lecture video. However, researchers also found out that, the research result is influenced by their measurement, "Wikipedia articles are longer, on average, than Britannica articles, and on a per word basis Wikipedia is actually slightly less biased. Wikipedia articles which have received more revisions tend to be more neutral. The more the crowd works on an article, the less biased it is."

In the whole article, there's one quote from Clive Thompson got my attention, "Twitter is the place where you could be like 'here's my one thought' and then link somewhere. I no longer needed to write a one-paragraph blog post about it, and Twitter scratched that itch and gave it a larger audience than it might have had." While people addict to twitter for fun, the fact is Twitter is actually a very good platform to share and learn knowledge.

For the topic of whether you like physical book or ebooks, we have discussed a lot during our class discussion. And the result is, all people prefer physical book other than ebook, the main reason that people said for their choices is the same one, the reading speed could be much faster when they are reading with ebook because they are scanning the texts in the device, however, by this way, they don't remember much about what they just read and have to read again and again in order to understand what the content is talking about. Reading with physical book make them feel more comfortable that they can take some notes in the margin of the book and they all like the texture of physical book.

A lot of kids use smartphones or tablet everyday, and they even do not need their parents to tell them how to use these devices, it is like kids have the innate ability to use the technological devices. There are debates on whether touchscreen technology is good or bad for kids. For my personal opinion, touchscreen technology would make them lack communication skill and social skill. However, by providing sound effects, colours and moving objects on the screen, it could get kids' attention and interest to learn something they feel really boring such as math, by this way they could learn faster and understand better. Therefore, touchscreen technology is not totally bad or good for kids, it depends on how parents help kids to balance how much time they could spend on touchscreen technology. It seems the only way for kids, because they are too young to have self control.
