Free wiki software

Hardly anyone who surfs the internet has not seen Wikipedia. Still many people are unaware of the etymology of the name. The term wiki was actually coined by Ward Cunningham in 1995 when he wanted to create a website for common programming patterns. He chose the word "wiki" which means fast in Hawaiian, a dying language. Ward's wiki was a big success and is still used today. Six years later Jimmy Wales started Wikipedia, which was actually a side project of Nupedia, which was supposed to be a serious encyclopedia written by professors and PhDs. Nupedia never reached a 1000 articles. Wikipedia is now in the top 5 of most visited websites.

So if you want to set up your own wiki, you can.

MediaWiki

Wikipedia is running solely on open source software. MediaWiki is the specific wiki platform that grew with Wikipedia. It's great software with some quirks. Say you want to for example run a private wiki, with MediaWiki your wiki has to be entirely private. Or entire public. You can hack your way around it but there will be leaks.

Dokuwiki

I'm personally not a fan of DokuWiki but it is very common software, and it's good if you want to have your wiki partly private.

Meteorpedia

Meteor is an awesome realtime JavaScript everywhere platform. It's not so great for SEO but it's the future. Meteorpedia is a wiki built in Meteor.

A moneyless world

A moneyless society is a very utopian idea. Nevertheless human beings were living in a world without money at some point in the past. According to Wikipedia money emerged already around 12,000 BC. Though the first coins have been created quite a bit later.

Free public transport

In most places it's still a far stretch but there will be a day that public transport is freely accessible. In some cities it's already happening and for some people in some Western places, but free public transport is still something to work towards.

Free wiki hosting

Wikis are great ways to structure knowledge together with other people. Wiki means fast in Hawaiian, which is for a reason. I've written a little overview of free wiki software, now it's time for free wiki hosting. Unfortunately spammers have also found ways to use wikis, mainly for black hat SEO linkbuilding purposes. This makes it pretty hard to keep a community wiki running.

Free pictures

When creating online and offline material it's very important to add pictures. It's easy to find pictures through Google Image search. Unfortunately it's not legal to use most of these pictures for any purpose. You could instead opt to pay for royalty free pictures, but this costs money and it's even tedious to sign up and deal it.
