Here i wanna talk about web1.0, web 2.0 and web 3.0.

Web 1.0. The first generation of internet sites primarily gave information. With the rise of Facebook and Amazon the web had become increasingly interactive.

In web 2.0 it's mostly the user produces the content, without contributes there would be no Facebook and no interactions on youtube and wikipedia. Most people have become more familiar with web 2.0(blogging, tagging, social networking)

Web 3.0 is a continuation of existing technics. You can listen online the music that caters to your personal wishes. The internet is a web full of appliances that communicate with each other by exchanging information. 

Also i wanna talk about the abb called "Second life" for language learning.

It is a good abb and you can ask in a chat everything you don't understand , people usually help you. Here you are given the activity, so you can communicate with others on certain language. There are games with consequences and all fun activities make people relax. You mantain you contact with native speakers. This game provide you an access to some exercises with the language that you learn.
