You can see how Jesse is using TAGGING in his post.
Tagging allows you to search and find content within a blog or webpage.
If you tag your post then you can jump right to points as you blog gets larger.
Newest thing on internet is Tagging Photos... so as stuff is uploaded you know your picture went up.
Also... if go into the post setting you can see how some are using the date/scheduling feature to pre set post so they will go online when needed. You can pre set your class...
* be careful of links, videos, pictures I tend to download the content rather then just linking in case content changes or disappears
