The World Wide Web is made of all the web sites that are publicly accessible.

Some of the web sites ask for a subscription to process a part or all of the content present there. For example, a lot of business sites are subscription sites, as well as gaming sites, academic journal sites, a part of many news sites, social networking web sites, web-based e-mail, sites that provide real-time stock market data, services and message boards.

There are many opinions concerning the 50 coolest sites in the world. According to Time, in partnership with CNN, for example, the 50 best web sites are the ones presented below. They are web sites that will require the erasing of your bookmarks, as they say joking around.

Starting with the bottom, with the one at the end of the list, Know Your Meme is the favorite dish of the fledgling. Weekly or seldom, “researchers” from the  Rocketboom Institute for Internet Studies give details about what is amusing on the Internet and why.

Get High Now is the next in the reversed list. Do not let the name fool you, because such a thing has not been invented, at least, not yet. The web site is actually a science site wearing a mask of mind- expansion. There are 40 visual and audio illusions or hallucinations that wait for you to experience them and understand them after they are explained through brain science. For example, even if they do not change the key, the Shepard tones arrive at a lower and lower or higher and higher tone. The Risset rhythms appear to have a faster and faster pace, but if you tape them with your foot, you notice they have never changed to start from. Theta-wave synchronizations and binaural beats give you a different state, and it is true, because you can see the induced changes through fMRI. A secret to science, the highly intoxicating chronosynclastic infundibulum is also presented on the web site.

Fonolo is a web site that will make you forget about the tiresome “Press one for English”. If you have had it with the impersonal, annoying corporations, Fonolo presses some buttons for you and remains on hold until someone in flesh and bones comes to speak to you. You phone then rings and you can talk to that person. You can even record the chatting as an MP3.

Going to the middle of the arrangement, skipping WorldWideTelescope, OMGPOP, Photosynth, Issuu, drop.io, Aardvark, TripIt, Mint, BabyNameWizard.com’s NameVoyager, CouchSurfing, Visuwords, Yelp, Supercook, Spotify, Musicovery, Pandora and Last.fm, Facebook, Pollster, Metacritic, ConsumerSearch, Kiva and Internet Archive, we find Wikipedia, the good old encyclopedia where anybody can edit and update the information.

Like in the Olympics, we skip over to the third place, leaving Redfin, PropertyShark.com, Etsy, Netflix, Kayak, Amazon, Shop Goodwill, Craiglook, Fora TV, Vimeo, Hulu, Wolfram | Alpha, YouTube, Google, OpenTable, Academic Earth, Boing Boing, Skype, Twitter, popurls and Metafilter aside.

Delicious (once del.icio.us), began as a sort of the Flickr of bookmarks, both being owned by Yahoo!. Now it is more helpful as a search-engine hack. By filtering the tags of the web site, you narrow it down to the kind of content you are looking for.

The second site, California Coastline by its name, is a must for those who try to conquer the sky, although it is definitely NSFW. One of the most riveting sites on the Internet is created using only a digital camera, a helicopter and a man. The web site is rudimentary, it does not want to show off with its interface, but with what is says to be – 10,000 up-close-and-personal shots from the air of the entire 1,000-mile-long coast.

You would have expected it or not, but Times’ number one choice in the list of 50 coolest web sites is Flickr. It was the first site that solved the computers’ problems with visual imagery, using the so- called  collaborative tagging. The main point is that everybody can tag everybody’s uploaded photos, then they will enter in a category created by the crowd. The archive of Flickr has almost 3 billion photos. As a cool fact, the Library of Congress has begun to poll the Flickr hive mind when it arranges its personal photos.
