Rahul Gupta has posted a javascript that goes into your template, & will force the blogger link field to output the del.icio.us tags that you need for categories. Three steps to make it work:

1. Turn the link field on (Dashboard > Settings > Formatting > Show Link Field)
   
2. Paste the script into your template
3. Edit the script to point to your del.icio.us account instead of Rahul's.

This way you can tag as you write your post. You'll still need to bookmark the post to your account, but you can tag as you compose. This basically duplicates the function of the greasemonkey method, but if you're not on firefox, or if you'd rather hack your template than your browser, this is the way to go.

Thanks, Rahul!!

Update 11/30: In the comments on Rahul's blog, Greg points out that this may not be the best thing for visibility on Technorati, & suggests a fix.
