http://en.wikipedia.org/wiki/Social_networking

and has over 900 million active members worldwide.

2003.

of people they know and trust in business and interact with
them through the site.

for potential employees.


SCREEN SHOT
It asks the simple question “what are you doing?” and
allows users to answer.
People can subscribe to other people’s blogs and will
receive updates to the question “what are you doing.”
The point is to have many people subscribe you your
updates and use the site as a powerful marketing tool.
“We have two people, Bob and
Betty. Bob can follow Betty,
Betty can follow Bob and if they
both did that, they would be
following each other. That is
literally all there is to the
relationships between people in
Twitter.”
The ideal relationships are
when you have many followers
to yourself. This can be a
powerful marketing tool as
many subscribers see your
updates.
Google+ (pronounced and sometimes written as
Google Plus, sometimes abbreviated as G+) .
It is a multilingual social networking and identity
service owned and operated by Google.
It was launched in June 28, 2011.

Was built out of tools designed for an online multiplayer
game called “Game Neverending” that never took off.
In 2005 Yahoo acquired Ludicorp and Flickr. Flickr has
remained relatively separate from Yahoo other than
shared usernames.
Flickr sets itself apart with key features such as:
tags (descriptive and geographic)
marking photos as favorites
group photo pools

Digg is a community-based popularity website
with an emphasis on various topics, but
primarily on technology.
It combines social bookmarking, blogging, and
syndication with democratic editorial control.
News stories and websites are submitted by
users, and then promoted to the front page
through a user-based ranking system.
A new way to discover news and other stories
that may not be as “mainstream.”
Blogs
Short for “Web Log”
Some blogs are basically public online diaries, while
others offer news and commentary (usually
opinionated) about a certain topic of issue.
According to Wikipedia, Blogging can be divided in
three eras:
1994-2001: Online Diary Stage
2001-2004: Blogs gain legitimacy
2004-Present: Blogs become mainstream
Blogs
Blogs give a voice to anyone and allow more
interaction worldwide than ever.

Wikipedia
Controversy has arisen over the accuracy of
Wikipedia articles since people can post incorrect

Community standards keep accuracy high as

factually know comes out
If something is blatantly wrong, rarely does it go
unnoticed and it’s never long before it’s corrected.

Pros of Web 2.0
The increased cross functionality through API’s and
other technology.
Increased community and social interaction leads to
more accurate, interesting, and diverse uses of the
web.
Web 2.0 applications have given a voice to those who
never had voice. The web reflects “the people.”
Web technology has grown increasingly fast through
Web 2.0 applications
Cons of Web 2.0
1. Web 2.0 apps use a lot of bandwidth, and eventually our
current infrastructure might not be able to take it. (Experts say
the Web will start to seem “pokey” as early as 2010, as use of interactive and
video-intensive services overwhelms local cable, phone and wireless Internet
providers)
2. In general, many feel that the whole move is just “hype” and
not much substance.
3. It’s kind of a double edged sword letting information fly
around from any individual or community, sometimes it can
be damaging.
The Future… What’s Next?
Web 3.0?
What do the experts think…?
Web 3.0
Eric Schmidt, CEO of Google says about the future and
“Web 3.0”
“my prediction would be that Web 3.0 will ultimately been seen as
applications which are pieced together. There are a number of characteristics:
the applications are relatively small, the data is in the cloud, the applications
can run on any device, PC or mobile phone, the applications are very fast and
they're very customizable. Furthermore, the applications are distributed
virally: literally by social networks, by email. You won't go to the store and
purchase them... That's a very different application model than we've ever
seen in computing.”
Web 3.0
Jerry Yang, founder and chief of Yahoo
“Web 2.0 is well documented and talked about. The power of the Net
reached a critical mass, with capabilities that can be done on a network level.
We are also seeing richer devices over last four years and richer ways of
interacting with the network, not only in hardware like game consoles and
mobile devices, but also in the software layer. You don't have to be a
computer scientist to create a program.
We are seeing that manifest in Web 2.0, and 3.0 will be a great extension of
that, a true communal medium…the distinction between professional, semiprofessional and consumers will get blurred, creating a network effect of
business and applications.
