I use w.bloggar to post 99% of the time. w.bloggar only lets you ping one site when you post so I chose to use ping-o-matic. But somewhere along that line, technorati was not getting pinged. So it never indexed my site with the tag links. Now that I changed it so w.bloggar pings technorati. My tags show up!!! Sweet.
Looking around Technorati I found this post about exporting your del.icio.us bookmarks. I’ll have to give these ideas a try.
