I've noticed that a lot of WordPress bloggers code each of their tags (keywords) for Technorati individually using the [tag][/tag] code – which takes more time than is necessary.
If you use the free Broobles » SimpleTags WordPress Plugin, you can save time by placing your comma-separated keywords and keyword phrases in one line at the bottom of your post in between the following code (without the quotes) – “[tags][/tags]“. Notice that you'll use the word ‘tags' instead of the singular ‘tag'.
Alternatively, if you're code-confident, you can modify the quicktags.js file to tag selected words using your QuickTags. The tutorial is located here.
