Background
It is difficult say that Web 2.0 became the Web in social, because since the Web was born people could collaborate and communicate online, but one of the biggest successes with the Web 2.0 is simple: the easy way to do it!. Almost of the principal services of this generation are easy and free; for example, people can create a personal page with social networking sites or write online with blogs without knowledge of web programming or pay.
Status
Now we see the hit of social networkings sites like Facebook with 350 millions of users, if Facebook were a country, it would be the 4th largest in the world, amazing!, don’t you think?. And of course we’ve another good example of success but with a different type of communication, I’m talking about microblogging platforms like Twitter, that we respond a simple question: what do you doing?, and that simple question was adopted and also forgot it in the pass of the years. The different of social networks like Facebook and Twitter is in the way of people communicate (Facebook = Synchronous, Twitter = Asynchronous). The benefits of being a part of this sites are a lot, and of course you know them, but my favorites are the community, the social tools and the conversations, everything in real-time.
