I have done a report on Wikia Search for OhmyNews

This could be an example of Web 2 activity. So far the content on Wikia Search is not very good. But there is space for a short bit of text on each search term. For example organisation, learning, learning organisation, quality, whatever. And each bit of text can then be changed.
My own interest is to see if learning and quality turn up in the same wordcloud. So I will be following what turns up on Wikia Search. The search results are a bit of a lottery but can be augmented by comment.
