I believe in the link economy. Please feel free to link to our stories — it adds value to all producers of content. I believe you should play fair and encourage your readers to read-around to what others are producing if you use it and find it interesting.
I don’t believe you could or should charge others for simply linking to your content. Appropriate excerpting and referencing are not only acceptable, but encouraged. If someone wants to create a business on the back of others’ original content, the parties should have a business relationship that benefits both.
