Social Networking 3.0

A social network - is a kind od structure made of individuals or organizations that are tied by one or more specific types of relations, such as financial exchange, friendship, hate, trade, web links, hobbies, etc
In the Internet there exists a bunch of sites that propose to create social networks online:
myspace.com, secondlife.com, livejournal.com, facebook.com, etc…

Now we talk about the third generation of social-networking technology has hit the Web, and it's about content as much as contacts.

Read this article, that talks more in detail about it :
The idea of these companies was at the beginning to let users build online profiles that advertised their interests and to help them connect with friends and friends-of-friends around one of those interests -- whether it be finding a job, making a sale, or repairing an old motorcycle.
Not so popular at the beginning, now it has become a real business.
Now members are using their networks for practical purposes, like finding job candidates, locating business and legal services, coordinating group activities, promoting its company, association or organization. It connects people and it has become really a personal media, and it is free!!! People share opinions, pictures and videos.
iMeem, relatively new social network company hopes to attract members by building all their activities not around a virtual representation of their social network, but around instant messaging technology. Indeed, the company's name is a combination of IM, for instant messaging, and "meme," meaning an idea spreading through a network. In terms of technology use they are leapfrogging all the older competition.
iMeem is built around a buddy-list window that shows a user which of her friends are online. From that window, she can send and receive instant messages, join group chats, keep a blog, and share photos, videos, podcasts, playlists, and the like with other users using a peer-to-peer system related to the technology behind the original Napster.
I think it really has a future, because there are so many programs out there, computer is overloaded, people have to long on to so many things. Whereas if we will have all-in one it would just be great!
