Hi Harold, I can see the advantages of incorporating free tools that many staff members are already familiar with, like twitter, youtube, wikis, etc. It sure saves on the learning curve and getting people engaged. But your post seems to implicitly suggest a CMS is complex and is hard to use. This doesn't have to be the case. Combine the best of both worlds and configure your open source CMS like Drupal or Wordpress to integrate with these 'low barrier' tools. A good CMS is still crucial to tie all these tools (and content) together. The enhanced functionality of the CMS, like taxonomies & folksonomies will make a significant difference in terms of 'findability' of the content. You'll agree that Enterprise Knowledge Management isn't only about the most popular and most "shareable" content. Also, content creation/curation in an enterprise requires consistency (obtained through a good content strategy), even for its internal content, produced and curated by its own staff. That doesn't mean it needs to be centrally controlled, but it does require mechanisms to manage it. If not we're just creating "orphan content" that once outdated will become counterproductive.
