The productivity Web site Web Worker Daily had an interesting article last week on how to make money online--and, as it points out, they aren't talking about affiliate marketing sites or selling stuff on eBay.

I found the article to be pretty useful, and apparently a lot of other people agree--it has gotten more than 1,900 diggs on Digg.com. It offers ideas including the following, and gives links to sites to find more info on them:

• Offer your professional expertise in an online marketplace, whether it's writing, programming or consulting
  
• Sell photos on stock photography sites
  
• Blog for pay at sites that need content
  
• Provide service and support for open source software
  
• Online life coaching
  
• Work as a virtual assistant
  
• Build services atop Amazon Web Services
  
• Write reviews for pay or perks
  

Aside from this article, Web Worker Daily has a good collection of articles on different aspects of being online and getting things done online. In some ways it's like Lifehacker, which I wrote about last week, but is more focused on the Web and technology.

WWD has articles on topics such as working styles, tech gear, how-to's, personal organization, applications, style and etiquette, tips and tricks, and workplace trends. I enjoyed the recent article about reusable batteries that can be recharged in your laptop's USB port.
