What's happened with Technorati?

I can't ping Technorati to announce my new postings!! Is there anybody out there who can offer any suggestions to fix the problem?

When I ping technorati, my last post was 260 days ago or so. Even though I have just posted new contents. A delay of a couple of days is still reasonable. But the strange thing is this only happens with this blogs. My three other blogs are just fine.

Sigh.....
