I have been finding a lot of information on what tags are but can find very little on how to implement them (beyond references to plug-ins).
I am interested in tutorials and references that explain:
1) the differences in tags (e.g. how do the colored tags that show up behind the posts at WordPress -> new tags page -> open source differ from technorati tags)?
2) what is the syntax and procedure for tagging words in your blog
3) how do you let the various tag aggregators know you've posted a tagged blog.
Looking forward to your responses
