There are scripts out there to make tags that are good for either del.icio.us or Technorati. Either one adds a tag generator to the blogger new post form. To streamline the process, here's an edited script to make a single set of tags that are good for Technorati and Delicious. This works because Technorati tags don't have to link to technorati. They can link to del.icio.us and technorati will find them because of the rel: tag attribute. One set of tags is therefore capable of doing two things!!
The script makes tags that are grammatically correct for technorati but actually link to del.icio.us. Please edit it to replace my del.icio.us username with yours, try it out, & let me know whether it works....
I'm watching technorati to see whether this post shows up in their tag results...
And it works!! As a side note, it looks like you can drill back further in technorati tag searches now, so scroll down the Mozilla results to see this post!!
Ignore my jabber in the comments. Technorati can see multiple tags from this script just fine... it just takes a sec, and I have no patience....Update 7/16:
I've written a more detailed & hopefully more helpful how-to for this method now that I've been using it for a few weeks.
Update 7/23:The script is now listed on Greasemonkeyed.com. Awesome.
