Web 2.0

Basically, the Web 2.0 is a new style of using the Internet. Before now, the Internet was like a big library that had a lot of information. However, nowadays it is seen as a new means of communication. It is a place where people can share information. Moreover, the web is based in communities of users where they share information with the help of blogs, wikis and social-networking sites.

In times of the web 1.0 the user only downloaded  finished webs. But now apart from doing that ,they also do personal contents. For that reason we can say that with web 2.0 the user is more active. There are several causes that can explain this involvement of the user with the web: the increasingly number of users, the broadband…So the web 2.0 is not a technology, is an attitude from the users.

 

WordPress is one of the blogs that people use for

sharing information.

 The  man who established this term was Tim O’ Reilly in the year 1993. He wanted the people to know that the content was not text, it was a way of interact between the users. Nevertheless,It was not after the O’ Reilly Media web 2.0 conference in 2004 that the concept became notable. According to Tim O’ Reilly:

                                                 “ Web 2.0 is the business revolution in the computer industry caused by the move to the Internet as a platform, and an attempt to understand the rules for success on that new platform”

Hypertext

Mainly, when we talk about hypertext we talk about a text that lead us to another text which is linked to the first one. We are transported from one page to another by hyperlinks. Not only do these links show us another text but they can also show us a video, song, web page…related with the subject.

Hypertext has renewed the way the user has to read an article, has improved  the way of getting information and has finished with the limitations of written text. Nowadays, with hypertext we do not have to read the whole article, we just read what its useful for us and click on an hyperlink to continue reading about what we are interested. The user read the information in a non-lineal way and each user can read the information in the way he want. For example, while I am writing this article, I am searching the data which is going to help me surfing from web to web but maybe another person may do it in a different order.

 

 This is the way we read with hypertext.All the web is connected.

There are two men extremely connected with hypertext who are  Ted Nelson and Vannevar Bush.Vannevar Bush wrote an article that established the basis of the hypertext in his article”As We May Think” and Ted Nelson coined the terms hypertext and hypermedia.

Finally, People has to do an effort and try to get used to hypertext. It is not like written text, you have to be more attentive to ideas in order to be able to catch the specific information you want.

RSS

The Internet is developing in a very fast way. There are appearing new instruments that help us to use it more easily and faster. One of these instruments is RSS. This instrument is a format based in XML and allows you to get up-to-date  informationwithout having to go to all the blogs you normally go. It has to be said that there exist three types of format RSS( Rich Site Summary, RDF Site Summary and Really Simple Syndication) and his initials acquire a different meaning depending which one you are using.

RSS SYMBOL

RSS has changed the way we use Internet. Before now, we had to go to every single blog to see if there was new information.It was frustrating when there were no changes and we have gone there for nothing. However, nowadays the news come to us.The RSS has helped us to earn time and not wasting it .

But how does RSS work?If you want to use RSS, you will have to follow these steps.Firstly, you need a RSS reader like Google reader(there are more RSS readers but this is a good one). Then, you create an account in Google reader and go to your favourite blogs. Finally, when you are in the blogs you only have to copy the feedsand add them to Google reader. You will only have to go to Google reader to see if there have been changes in your favourite blogs.

This method is very useful and more and more people are starting to use it. Try to get used  to the symbol of the photograph because you are going to see  it many times.
