Social Media

Social media is media that is broadcast through social interaction. It has changed how we broadcast traditional media in a huge way. Social media is appealing to big businesses and credible brands are using it as a form of advertisement. Social media is also being use by everyday people to share news about themselves to people within their network.
Social media has tremendous reach, it enables anyone to reach out to a global audience. Anyone with a computer and an internet connection can have access to your post. Traditional media is owned by the publisher or by the government, however social media is available to everyone at little or no cost at all. Most social networking sites are free for anyone to signup. Social media is also instantaneously, there is no time lag between publishing and receiving. Also, social media can be edited by the publisher even it has been published, whereas traditional media cannot be edited once published.
Social media can take many different forms, including Internet forums, weblogs, social blogs, microblogging, wikis, podcasts, pictures, video, rating and social bookmarking. Technologies include: blogs, picture-sharing, vlogs, wall-postings, email, instant messaging, music-sharing, crowdsourcing, and voice over IP, to name a few. Many of these social media services can be integrated via social network aggregation platforms like Mybloglog and Plaxo.
Web 3.0
Web 3.0 will be about semantic web, personalization, intelligent search and behavioral advertising. By opening up access to information, Web 3.0 applications can run on any device, computer, or mobile phone. Applications can be very fast and customizable. Unlike Web 2.0, where programs such as Facebook and MySpace exist in separate silos, Web 3.0 allows users to roam freely from database to database, program to program. Web 3.0 uses structured data records published to the Web in reusable and remote-queriable formats. XML technologies such as RDF Schema, OWL, SPARQL will make this possible by allowing information to be read across different programs across the web. Instead of searching the web and spending hours filtering the information we need, web 3.0 knows what we are looking for and searches the net for information then present to us the information that suites our needs.

RSS
RSS stands for really simple syndication, it is a way to subscribe to a source of information such as a website and brief updates will be delivered to you. These sources are called feeds. When you subscribe, you'll get a feed -- often a series of headlines and brief summaries -- of all the articles published on that particular Web page. This lets you scan the articles on the page more efficiently. Sometimes you'll even spot more headlines that you might never have seen buried on the original page.
