I had an idea while writing a blog about baseball the other day. A ‘suggested tags’ option. Similar to the ‘most used tags’ sidebar, this would quickly scan your blog entry and suggest certain tags for you depending on the content. For example, if you mention baseball, as I did, the ‘suggested tags’ sidebar would say “MLB” “Baseball” “Yankees” “Red Sox” etc., most looked at tags depending on the topic.
I think it could revolutionize the way WordPress works as well as make the interface for the bloggers more simple.
