[Added 12 December 2005:] NB The script mentioned in this post has been updated and enhanced, please see this post instead now.
Anyway, to use Greasemonkey you have to first install that extension from the Greasemonkey site (Firefox users should be familiar with how - click the Greasemonkey extension link, if nothing happens and you see just below your tabs a message in horizontal bar that "To protect your computer, Firefox prevented this site (greasemonkey.mozdev.org) from installing software on your computer", you should click "Edit Options" at the end, then "Allow" and "OK" to allow that site to install software, then try clicking the Greasemonkey extension link again, give it a few seconds then click "Install now". Close and re-launch Firefox.)
Then you install the appropriate user script (Greasemonkey won't do anything without a script). To install a script you click on the link to the script. When you're on that page (which looks like just a bunch of text), in your Firefox Tools menu choose Install User Script. Alternatively you can just rightclick on the link to the script and choose Install User Script. (Beware though, not all scripts will be innocent, some could wreak havoc if malicious!).
The definitive list of Greasemonkey scripts seems to be at GreaseMonkeyUserScripts (though not all scripts are listed there [added 12 December 2005:] - now see Userscripts.org), so even if you can't write scripts you can easily make use of the large and growing library of useful scripts.
For the addon to help you create Technorati tags if you're using Blogger.com as your blogging platform, the script that's of interest is by Fabricio Zuardi - I use the version amended by Bryan Price and they're conveniently listed on this post on False Positives who also modified the script to produce a version that outputs Del.icio.us tags (note that using that version doesn't add your post to Delicious's tag pages, it just provides clickable links to those pages whose tags you list - you still have to bookmark your post separately - to help speed up that process, see this post).
[Edited 9 July 2005:] Now Truckspy has modified the script so it can handle multiple word tags, see this post. [Added 12 December 2005:] The script mentioned in this post has been updated and enhanced, please see this post instead now.
What this script does is to change your "Create post" page on Blogger to add an extra line after the box where you write the post, which looks like this:
To add Technorati tags to your post you just type in the tags you want, separated by spaces, and click "Append Tags" and it will add to the end of your post something which looks like the following, with the correct Technorati format behind the scenes (where the tags you've entered are "test" and "test2") (I've not included the tag stuff for this as I don't want this post to get tagged with "test", this is just to show you what it would look like!):
Tags: test test2
For those interested, the code it adds is in fact the following, so you can create a "tag_list" class and style it, and you also could edit what it adds by editing the script:To use multiple word tags I run the words together when I enter them, then edit the post to insert a space in the link text and a "+" in the "rel" bit in the appropriate places (see my intro to Technorati tags, which I've edited to add a note about this tool, for a fuller explanation). [Edited 9 July 2005:] Now Truckspy has modified the script so it can handle multiple word tags, see this post.<div class="tag_list">Tags: <span><a href="http://technorati.com/tag/test" rel="tag">test</a> <a href="http://technorati.com/tag/test2" rel="tag">test2</a> </span></div>
Note though that the tool only works when you're in the "Edit HTML" view, not the "Compose" view of Blogger. You need to change to the Edit HTML tab if you find yourself repeatedly clicking "Append" to no avail!
(I first saw mention of this tool on Oui-Blog - not that I could read that post, but I got the picture, literally!)
