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.

Flickr has remained relatively separate from Yahoo other than shared usernames.Flickr sets itself apart with key features such as:

A new way to discover news and other stories that may not be as “mainstream.”
BlogsShort 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 Stage2001-2004: Blogs gain legitimacy2004-Present: Blogs become mainstream

WikipediaControversy has arisen over the accuracy of Wikipedia articles since people can post incorrect and inaccurate informationCommunity standards keep accuracy high as people’s genuine desire to write about what they factually know comes outIf something is blatantly wrong, rarely does it go unnoticed and it’s never long before it’s corrected.

Acquired Skype in 2005
Software program that lets users make phone calls from their computers using Voice Over IP
Members can talk to each other for free and can call landlines and cell phones for a fee
Uses the world wide web to increase communication
People without standard phone lines can still connect to each other
Differs from similar programs because it is Peer-to-Peer not server-client based
Pros of Web 2.0The 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 2.01. 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 3.0Eric 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 3.0Jerry 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, semi-professional and consumers will get blurred, creating a network effect of business and applications.
