Taxonomy expert Stephanie Lemieux (Earley & Associates) and I had a great Skype discussion about creating and managing content types in SharePoint. The conversation centered around whether you should create lots of content types, supporting a very granular taxonomy of documents or creating fewer content types, supporting a larger variety of documents. Stephanie published a great blog article about it on her blog.
Stephanie and I both concluded that fewer content types is probably a far better bet. In fact, there are both taxonomic and technical reasons supporting our position. From a content management perspective, content management guru Bob Boiko had a great quote in the article:
"How many content types is the right number? The fewest possible to squeeze the most value out of the info you possess.”
