Social Networks:


1/ In my opinion, Social Networks is a real E-Business. We saw thanks to some examples of social networks sites that it allowed people to do many interesting things easily, clearly.., meeting other people, having many information about various subjects like travelling, asking about a city or countries, and specially people can tell about an experience in a foreign country..
Other things are: shopping, find several information about things daily used, sharing pictures.


2/ I think that social networks are made especially for single people, but not only, because every one can share information or ask about information about travelling or other things thanks to this site. People can by things tanks to this site. So, as far as social networks as concerned, I think that this site can be used by every one who feels like needing to share information, to meet people, friends, lovers, or to do shopping.



3/ In my opinion it’s trendy and real in the same time, why? Because nowadays, most people use this kind of sites, but it’s so interesting to use them, it helps us to have information we need, to share pictures, to meet the others, to ask questions, to buy things, briefly, it helps us a lot.

A social network is a social structure made of nodes (which are generally individuals or organizations) that are tied by one or more specific types of relations, such as financial exchange, friends, kinship, dislike, trade, web links, sexual relations, disease transmission ,or airline routes.
Social network analysis views social relationships in terms of nodes and ties. Nodes are the individual actors within the networks, and ties are the relationships between the actors. There can be many kinds of ties between the nodes. Research in a number of academic fields has shown that social networks operate on many levels, from families up to the level of nations, and play a critical role in determining the way problems are solved, organizations are run, and the degree to which individuals succeed in achieving their goals.
In its simplest form, a social network is a map of all of the relevant ties between the nodes being studied. The network can also be used to determine the social capital of individual actors. These concepts are often displayed in a social network diagram, where nodes are the points and ties are the lines.


An example for social network : www.voila.fr.

the site use value to users because it allowe them to meet people, to buy things, to have information about traveling, phone numbers, weather,....

The difference between this site and others is that we can meet people, we specialy can chat with people, it means speak to people connected in the same time. there is an area about having information about traveling, we can do shopping thanks to this site.

Revenue streams: Content organizations must constantly consider how to better monetize traffic to diversify their revenue streams. Yes, online advertising is still growing at a good clip, but that won't continue forever. Healthy ad growth is no reason to ignore opportunities to build a brand and increase revenues by broadening offerings. This is particularly important for online divisions of traditional media companies, which are losing more profitable audiences from older media formats, causing revenue shortfalls.
Online content providers have three ways to increase bottom-line revenues: expand ad sales, increase paid subscribers, and develop related paid products. In the current market, single-mindedly focusing on building an advertising base may seem like the way to go. Although this strategically positions you to take advantage of current market conditions, it's shortsighted. The ad market could change at any time. It's therefore important to have a mix of revenue streams.

1/ 3 additional revenue sources are :

- discussion with people ( like MSN, )
- sending e-mails ( hotmail, yahoo) very important in this moment even for job or personal use.
- Bye air-tiket and spécialy choose interisting prices thanks to different sites ( Kelkoo, Expédia,..)


2/ Seggments are replaced by new ideas, by understinding clients need, by using managment to develop or to create a new nedds, to replace an old products, to push people to bye, to accept new ideas. Sometimes, we just have to renovate a product that it exist already in the past, but we had to change it, to offer it in new way. Clients needs innovations, needs to feel themselves following fachion in some cases, so managers ou sales men or women have to keep it new, beautiful, available and attractive, because people needs new things in their life, I know that i need new things in my life very often.
That 's very important to digital economy because it puch it to work, it keep it doing well, it keep having buyers, and economy need that.


3/ FREE can generate revenue by lating people to test a product, to khow how it works, then the user can be clients because he will need to use the second part of the product, he'll be interested in having the compleete program for example, people like to renovate, so once they use a product for a moment, they need to change it so when internet propose a program easy to use ( thanks to the free part), not expansive, in most of time they buy it, because they need to be like the others.
For me, i had to buy the new program of MSN Mesanger because i want to have all options, to have the one with a lot of interesting things, to be like my freinds, to be IN.
