Tag – You’re It

As a relatively new blogger, the details of reaching out on line elude me. I can add a photo and write a post and even link to another site, but tagging and kick backs and pings and metadata and all of the other stuff is over my head.
Today I read a post by Mike Sansone of Converstations entitled, Hey Coach, What's a Tag?
Did you know that tags and key words are different?
He referenced an article entitled Tagging- How to deliver your content effectively and Technorati that provides interesting information and instruction on what tags are and how to effectively use them.
Give it a read. Unless you are way more evolved than I in the blogosphere -which wouldn't be hard to do and in that case – do you give lessons?
How have tags worked for you?
