Produsage in my profession

The concept of produsage is already being used to a certain degree professionally by the company I work for – Citrus County Chronicle. One example is the letters to the editor. This is content strictly produced by users who do not get paid for their work and decide on their own to contribute the content to the newspaper, which aggregates and publishes the letters. The newspaper, though, applies filtering rules to the content. Letters cannot be over a certain length and must be of good taste and not slander another person. Another method of produsage is our Sound Off section. We have a dedicated phone line that tapes calls from users who sound off about any topic they choose. The user has the freedom to speak on any topic or issue and can remain anonymous. Again, these items are filtered before being used commercially by the newspaper. Comments cannot exceed one minute in length and must be in good taste and not slander another person.
The question you might have is how are they improving or building on a product? My answer would be that they are providing content in the form of opinion, much like a blogger does and those who comment on that blog. This content is something consumers want (according to our surveys, the opinion section of the newspaper is one of our highest read and many people buy the newspaper just for that section).
