This is a introductory guide to "tags" on Technorati,
the blogosphere search engine, which started using them in mid-January
2005. It’s a practical introduction rather than a tutorial (ending with
some personal thoughts about tags), but I’ll summarise the basics about
Technorati tags and how to use them in your own blog posts – stuff I’ve
learned from digging around, playing around and, as you’ll see later,
much tearing out of hair. I do assume knowledge of basic HTML (for
which see e.g. this or this), but if anything needs to be made clearer or expanded upon, please post a comment and I’ll try to help.
If you are looking for a fairly comprehensive guide to Technorati tags, be prepared for A Consuming Experience.
