Squidoo and Hubpages. These sites are communities of article writers that build article pages using content modules which are then published as micro-sites.
The latests article writing community to gather some traction is Wizzley. Similar to Squidoo and Hubpages you are responsible for generating article content on topics that you know about or find interesting. Your hard work as an article writer is rewarded by getting income from context adverts via Adsense that are placed with your articles and also through affiliate modules such as Amazon Associates, Zazzle the print on demand site and Allposters.
The user interface is really easy to use, you can add your photos and images to text modules to really bring your writing to life and there is a rapidly growing and vibrant community of supportive and friendly writers there too. It seems cliched to say it but of course 'content is king'. Why else would anyone want to search for and read what you have to say?
One of the good things about Wizzley as an article writing platform is that is emphasizes content. You are given a word counter that requires a decent amount of article content wordage before your article can be published. And that's not all the revenue share set up is favorable to the article writer.
