Hi Jocelyn Flint,
You are correct. To get unique views, you will need to use Data Feeds and modify the queries a bit. For example, upon loading the fContentBlog table, getting unique pairings of the user_key and blog_key columns would result in unique rows for that user, for that blog.
We currently have the Unique View Counts report that allows you to pull back unique views on a given content type. However, it may be worthwhile including this information in some of our other activity reports (e.g., Blog Article Activity report) as well so you can get this on a blog article-by-article basis, for example.
