Social Networking and Web 3.0

'If Facebook was a country, it will be fourth largest in the world'. Such is
the volume and usage of social networking sites among organizations. While some
companies use Linkedin to find prospective employees, others use Twitter or
other social network to capture new customers. The potentials of social networks
have become clear to companies, and thus is the adoption of multiple social
networks by organizations  for purposes ranging from collaboration to promotion
of their brands. Here, we take a look at some of the upcoming trends and
technologies in social networking, and how is Web 3.0 going to change the
landscape.

While it's  hard to predict what the future of Web would look like, one thing
is apparent. Today you don't  need a PC or a laptop to browse Web. Browsers have
reached almost everywhere —right from mobile devices to gaming consoles (Wii and
PS3) to even television. Even in places where there is no browser (as yet) such
as Xbox360, Twitter and Facebook have already made their way to. New firmware of
PS3  also as Facebook. Social networking vendors are making sure that you can
access them from where you are, without needing a computing device.

Everything mobile

One of the key reasons why microblogging got so popular so quickly has been
that, the vendors in the space have targeted mobile users since beginning. They
realized that, for a person to fully utilize the power of social networking, he
should be able to update his microblogs from anywhere and at  anytime. Even
today majority of Twitter usage comes from mobile devices.With social networks
leveraging mobile devices more and more, location based social networking is
also gaining momentum. In a research done last year by ABI Research, location
based social networking is expected to be a $3.3 billion market by 2013.

Twitter would be launching geo-tweets very soon, which will allow users to
embed their location with their tweets. Similarly a company called PhotoWALL
displays real-time media streams (or WALLs) by presenting live media precisely
when it happens. It allows mobile users to send live photos along with various
geo-tags and VoiceTags to an attractive searchable website for public, network
or private viewing.  It also enables simultaneous live uploading of mobile media
to Facebook, Flickr and Twitter. It was launched in India last month with MSN
India and is available  http://msn.photowall.com. Location based social
networking also opens a whole new range of possibilities such as location based
advertising, finding like-minded people who are near to you, recommending places
to friends, finding reviews what people around you have to say about a
particular place or product, etc.

Social TV

Television is mostly enjoyed to its fullest, when it's watched with friends
and family. And one can't always be around friends or like minded people to
fully enjoy a show or game. But now things are starting to change, TV is not
only going interactive but is also getting social. There are quite a few models
starting to come in this area. Orange has tied up with Twitter to improve
Twitter experience  for its mobile, Internet and TV users.  As part of the deal,
Twitter will be integrated into Orange's IPTV platform and Twitter feeds will
run alongside programs to create an interactive environment.  Another approach
that is coming up is in the form of Social TV widgets or just TV widgets.
Verizon's FiOS TV already provides Facebook and Twitter widgets to its
subscribers. Also earlier this year, Yahoo!  tied with Samsung, Sony, LG and
Vizio to provide TV widgets for their televisions sets, popularly known as Yahoo
connected TV. Similarly there are companies who are offering software that bring
social networking to set top boxes.

A slightly different example is  Clikthrough (www.clikthrough.com), which
makes watching videos online even more interactive. Videos hosted on the website
have 'hotspots'; if someone clicks on  the  hotspots, they can view information
like comments made by others about that video, products used in the video,
people present in the video, etc. You can even add the product in your wishlist.

Web 3.0

Web 3.0 is always an interesting area. We talked about web 3.0 or the
semantic web quite a few times earlier.  Semantic web refers to the study of
meaning and web-study of interlinked documents accessed via the Internet. Web
pages are generally written in HTML,which describes the structure of information
i.e the syntax but not the semantics. But if the computers can understand the
meaning behind the information then this can help us in a better way with
information that we are looking for.  There are quite a few Web 3.0 applications
we have been exposed to already including the likes of Twine, Google Squared, Mozilla Ubiquity,
etc. Also many regard Google Wave as the start of Web 3.0 wave. Last month, W3C
declared OWL 2 as a official standard as part of its Semantic Web toolkit. This
standard will help users to capture information of any domain and then use
semantic tools to search, manage and drive more data from it.

HTML 5 and CSS 3

Some say that XHTML is dead or not used at all and HTML 5 is taking over the
market.  Again, there are speculations that  HTML 5 won't completely be
supported until 2022. Does this mean that HTML 5 won't be widely adopted in near
future. For a web designer, who wants to play with HTML 5 and CSS 3, take full
advantages and explore new features which would be beneficial; so they must know
the new 'modules' or the elements. Though CSS 3 and HTML 5 is still not
implemented fully, one way to implement them is to use a Modernizr. The current
browsers don't support these new standards. Modernizr is a small, easy to use
and simple JavaScript Library that helps in taking the advantages of these new
technologies. Features like rgba(),border-radius, CSS transitions can be tested
for a particular browser using its own  feature detection technique.

Google, as they always keep on googling with the new technologies, has
recently launched Google Wave which uses HTML 5, in which they aim to control
the environment.

Safari also supports new elements of HTML 5 and API's, and is also a Webkit
browser that supports HTML 5. The Palm Pre, iPhone 3Gs and the new Google
Android phone all have browsers that are based on the Webkit rendering engine
that fully make use of HTML 5.

CSS3 (Cascading Style Sheet 3) is one of the new member in the style sheet
family. CSS is basically used to describe the presentation semantics of a
document that may be written in HTML, XHTML, XML documents including SVG and XUL.
The development of CSS3 is split  into different 'modules'. The old
specification was simply too large and complex to be updated as one. So it has
been broken down into smaller pieces — with new ones also added. Some of these
modules include; Box Model,  Lists Module and Hyperlink Presentation.  One of
the advantages CSS3 offers is its ability to handle multiple background images
per element. Another advantage is the use of separate stylesheet area which
provides an easier and comfortable HTML markup. The concept of differentiation
and isolation in CSS 3 helps users to have presentation separated from structure
so that for every heading in the HTML markup won't get repeated and thus making
it a easy, simple presentation with a low level maintenance.
