would say that Web 1.0 is the network where a business person, entrepreneur or state created static content via a website and users see the same and were created for simple navigation and information. Chronologically would be the first step in the evolution of the network and places it temporarily until 2001. Although this site currently features many SMEs 1.0 or users who only use it in a state of 1.0. Just read the news and send mail.

Then these concepts began to appear within site tools that make a revolution on the Web, an evolution of Google web 1.0 , Wikipedia, Ebay, Youtube, Skype, Writely, Blogger, RSS, Flickr, Emule, All these applications and sites have in common that their main asset is the user. A greater number of users increases the value of the site and its content. No versions, always changing. Web 2.0 is not intended to navigation but to the interaction. Has innovations (technologies).
But the main question we must ask which of these technologies will be appropriate tools to promote business (via advertising, information, contacts, boost productivity, improved labor standards)? And what applications are simply not sympathetic will overcome its function of entertainment?

So far what we were seeing is with respect to users, stating clearly what we are global trends. Some age groups are more rapid adoption of new types of Internet than others. A segment-level users and users participate in the WEB 1.0 other 2.0 and some more advanced everything is. For companies it is exactly the same number used technology much faster and are adhering to the tools 1.0, 2.0 and so on.
our analysis focused more on SMEs then we remember that more than ever, through crisis, SMEs do not have big budgets to digital media and are usually out there have no knowledge. What it should be clear that within this Internet is a mega trend in which there is no going back and changing the whole society which can not be excluded from it.
first thing to evaluate is our user customer or potential customer who has involvement in the WEB, if we see that our potential audience or much of it is in the Web 2.0 we should aim to meet and communicate in the same way . But obviously no step can be from nothing trying to create a community of users.
The following would be the first steps in the digital world:
1) Email
2) static or 1.0 Web Site
3) Corporate and Mailing Blog
4) Participation in Social Networking Tools 2.0, MSN corporate
Well
I think the issue is much deeper and can be extended but I wanted more than anything to make an approach to it. I welcome your questions or comments.
