What was once deemed an ideal of many societies, the internet was the first society of sorts to make the dream come true: FREEDOM FOR ALL.
Boon or bane, who is to decide? Fact is that whatever you are looking for on the (almost) world wide web, you are going to find it. And in the unlikely event that you don't find what you are looking for, you are most likely able to create it. Be it information, friends, love, collectibles, ideas, creative output, exotic insights or adventure, it's all there. There are no limits and everyone can participate in whatever they choose to share, accept or represent. Freedom for all.
Lately (legal) communities with a communistic sort of touch have surfaced the net with major success.

Communism isn't a new concept. Neither are helping each other without asking for anything back or giving something away for free. What is new is the amount of people and nationalities involved. The internet makes it possible. The net is an extremely powerful medium, which facilitates the interaction of human beings worldwide, in realtime, at almost no cost. Below are a few successfull examples.

CouchSurfing, from the CouchSurfing website:

CouchSurfing.com helps you make connections worldwide. You can use the network to meet people and then go and surf other members' couches! When you surf a couch, you are a guest at someone's house. They will provide you with some sort of accommodation, a penthouse apartment or maybe a back yard to pitch your tent in. Stays can be as short as a cup of coffee, a night or two, or even a few months or more. When you offer your couch, you have complete control of who visits. The possibilities are endless and completely up to you.

Geocaching is all about the hype created around navigation systems using ultra modern technology such as satellites, aka GPS (Global Positioning System). Via coordinates you can define an exact location everywhere on this planet. GeoCaching is about placing a box (aka cache) someplace secret. You then publish the coordinates of this place on the GeoChache website. People in your area are then able to find locations close-by and go treasure hunting. Of course you can do the same.

Geocaching, from Wikipedia, the free encyclopedia:

Geocaching is an outdoor activity that most often involves the use of a Global Positioning System ("GPS") receiver or traditional navigational techniques to find a "geocache" (or "cache") placed anywhere in the world. A typical cache is a small, waterproof container containing a logbook and "treasure", usually trinkets of little monetary value. Participants are called geocachers.

BookCrossing, from Wikipedia, the free encyclopedia:

BookCrossing, BC, BCing, or BXing, is defined as the practice of leaving a book in a public place to be picked up and read by others, who then do likewise. The idea is to release books into the "wild" to be found by other people, often strangers. The analogy is with the ornithological practice of ringing birds to track their movements.
If someone decides to release a book via the BookCrossing.com website, the book has to be registered in order to get a BCID (BookCrossing ID) number so it can be tracked. The person who finds or "catches" the book is then requested to log onto the BookCrossing web site and make a journal entry, and then pass on the book when he or she has finished reading it.
There are no charges for membership but donations received go towards the maintenance of the servers and continue the exile of pop-up ads from the website. Members who order BookCrossing items through the supply store or BC Newsstand will receive small golden wing symbols on the sides of their screennames.

Postcrossing, from Wikipedia, the free encyclopedia:

Postcrossing is a project, inspired by bookcrossing, designed to allow people to receive postcards from all over the world. Participants who send a postcard should receive at least one back, from a postcrosser in another country.

The Freecycle Network™ is a nonprofit movement, dedicated to the free exchange of anything people want to part with. Furniture, electronic devices, toys, clothes or old collections. It's subdivided into individual local groups, located across the globe. These groups are basically Yahoo Groups that are utilizing the eMail list feature. You may post OFFERED as well as WANTED items to the public list and anyone who is interested or can help out will contact you directly. The groups are moderated by local volunteers. Membership is - of course - free! If there is no group existing in your area, you can start your own group and add it to the Freecycle Network™.

For those left with no or only limited access to the internet, there are Freedom Toasters. They are CD/DVD burner stations where people who do not have access to the internet can obtain free software or information. All they need to do is locate the closest toaster, bring a CD or DVD, select the items they want to duplicate and have the toaster burn it on their CD or DVD. This service is free for all and people are encouraged to produce further copies to share with friends, family and the community. Naturally this medium can also be used by organizations to spread knowledge, communication technologies or Open Source software.
The project was originally started in 2004 by the Shuttleworth Foundation to provide people in South Africa with easy access to Linux and other Open Source software. It was necessary because the restrictive telecommunications environment in South Africa makes it impossible to download large pieces of software. Billions of people all over the world are faced with the same issue or don't have access to the internet at all.
The benefits are obvious. There is no need for Internet access, it's easy to deploy, easy to access, easy to use, it's capable of serving local and tailored content and it is a free and Open Source project.

I think this nicely sums up the possibilities of the internet. There are many more communities where people can share their skills or time. The ones described above are merely some of the most popular examples.
So, where do you want to go today? The possibilities are endless. Inside. Online. Worldwide.
