What about Bruns??? A few thoughts and questions?

What do you understand by the words ‘produser’, ‘produsage’, and ‘intercreativity’?

Prousers are involved in user-led content production. They represent a user of something (for example wikipedia) but also a producer of it. Other examples include
-Open news
-Open Source
- Open content repositories e.g wilkipedia and Flickr
- Collaborative knowledge communities e.g Google earth
- Produser communities round commercial products for example The Sims or remember Second Life we spoke about before.

Bruns definition states "The production of ideas takes place in a collaborative, participantory environment which breaks down the boundaries between producers and prousers of information and knowledge"

Produsage is the content that is produced by prousers. The concept of produsage highlights that within the communities which engage in the collaborative creation and extension of information and knowledge.
The title of one of Bruns books highlights three of the main types of produsage "Blogs, Wikipedia, Second Life, and Beyond: From Production to Produsage" This book captures a shift in cultural logic which is profoundly altering how culture gets produced.

Intercreativity - Am not overly sure about this one. I think it refers the creativity of interaction. For example the ability to be creative on websites like Second Life (building houses, casinos, people) but at the same time being interactive with other people on line.

Are they useful in understanding collaborative creation of content online?
Yes. Produsers tend to use a collection of other peoples work or content and bring it all together rather than work by themselves as individual content producers. Therefore produsage helps to describe the final production of this content with has been put together using the intercreativity of each online user.
