The first Web server: It is only 20 years ago!

 August 6, 2011 is the 20th anniversary of public Web service. According to Wiki:

Wiki: World Wide Web

... On August 6, 1991, he posted a short summary of the World Wide Web project on the alt.hypertext newsgroup.^[11]This date also marked the debut of the Web as a publicly available service on the Internet.

That is, in 1980's and before, it would be really difficult for people to imagine today's daily tools such as Portals, Directories, Search Engines, Wikis, and Social Networks.

Only 20 years! Amazing!

The world will surely evolve faster and faster. What would the world become 20 years later?! I cannot wait to see it!
