represent<strong>in</strong>g <strong>in</strong>formation that is accessed by means<br />
of classical protocols, hence, they are more languages<br />
than protocols, but, as they <strong>in</strong>clude state<br />
<strong>in</strong>formation <strong>and</strong> <strong>in</strong>structions for the access <strong>and</strong><br />
retrieval of <strong>in</strong>formation, they are usually known<br />
as protocols. Nowadays, Web service providers<br />
are us<strong>in</strong>g RSS/ATOM feeds as lightweight alternatives<br />
to SOAP. Developers are f<strong>in</strong>d<strong>in</strong>g new ways<br />
to comb<strong>in</strong>e Web services from different sites <strong>in</strong>to<br />
new applications, known as “mash-ups” <strong>in</strong> the<br />
l<strong>in</strong>go of Web 2.0.<br />
RSS states for Really Simple Syndication, <strong>and</strong>,<br />
<strong>in</strong>deed, it is. RSS is a very simple document that<br />
provides users with a title, an abstract <strong>and</strong> a l<strong>in</strong>k<br />
to the <strong>in</strong>formation. To overcome the limitations<br />
of such a simple solution, a more flexible <strong>and</strong><br />
powerful format have appeared with the name<br />
of ATOM.<br />
other networks <strong>in</strong> the network<br />
Although the Web is the most successful <strong>and</strong><br />
representative service <strong>in</strong> the Internet, we should<br />
not forget other <strong>in</strong>terest<strong>in</strong>g <strong>and</strong> very promis<strong>in</strong>g<br />
networked services that are also earn<strong>in</strong>g great<br />
acceptance <strong>and</strong> expectation.<br />
Peer to peer networks are frequently proposed<br />
as the alternative to a centralized <strong>and</strong> easy-to-control<br />
network. These services rely on the comput<strong>in</strong>g<br />
resources of every participant, <strong>in</strong>stead of rely<strong>in</strong>g<br />
on the giant servers of commercial providers.<br />
This approach allows support<strong>in</strong>g services with<br />
the resources provided by the users themselves.<br />
There are no scalability problems as newcomers<br />
contribute with new resources to the network.<br />
Some examples of this approach are file shar<strong>in</strong>g,<br />
<strong>in</strong> which b<strong>and</strong>width <strong>and</strong> storage are shared<br />
(eDonkey, eMule or BitTorrent), comput<strong>in</strong>g grid<br />
projects, <strong>in</strong> which spare comput<strong>in</strong>g time is shared<br />
(SETI at home or BOINC), <strong>and</strong> Internet telephony,<br />
<strong>in</strong> which b<strong>and</strong>width <strong>and</strong> geographical proximity<br />
are shared (Skype).<br />

the weB: weB 2.0 And the<br />
InFormAtIon socIety<br />
Web 2.0 affects all aspects of life, from the private<br />
<strong>and</strong> fun sphere to work environments, from an<br />
<strong>in</strong>dividual level to a group level. In short, Web<br />
2.0 becomes an enabler to (Pr<strong>in</strong>z, 2006):<br />
• Turn an Internet presence <strong>in</strong>to a customer<br />
experience site<br />
• Turn a passive consumer <strong>in</strong>to a creative<br />
content provider<br />
• Enforce the l<strong>in</strong>k between Internet users <strong>and</strong><br />
Internet places<br />
• Support the self-organisation of communities<br />
• Create a social Web on top of the technical<br />
Web<br />
Currently, we can access lots of <strong>in</strong>formation<br />
<strong>and</strong>, at the same time, write our own content or<br />
leave comments. We are now the content generators.<br />
Education, market<strong>in</strong>g, journalism, <strong>and</strong> even<br />
politics is mov<strong>in</strong>g towards the reality 2.0.<br />
Market<strong>in</strong>g 2.0 is about gett<strong>in</strong>g <strong>in</strong>tegrated <strong>in</strong>to<br />
the message “constellation” (Thorson, 2006). Web<br />
2.0 gives companies the opportunity to reach<br />
thous<strong>and</strong>s of customers at a much lower cost.<br />
Companies need to underst<strong>and</strong> that their customers<br />
are their best marketers; a positive comment<br />
about a product or service is still more powerful<br />
than any commercials or pr<strong>in</strong>t ads. Until now, those<br />
comments took place at cocktail parties, where<br />
very few people knew about them. However, now<br />
the place is the blogosphere, where everybody can<br />
read <strong>and</strong> comment about them. In this sense, Polo<br />
(2006) gives her op<strong>in</strong>ion about the power of blogs:<br />
“imag<strong>in</strong>e a database <strong>in</strong> which you can search lots<br />
of conversations about your products, with good<br />
<strong>and</strong> bad op<strong>in</strong>ions... terrify<strong>in</strong>g, isn’t it?”<br />
Another <strong>in</strong>terest<strong>in</strong>g example is journalism,
