Technorati is broken or just useless?

Well, technorati seems to not like my blog, it claims I haven't published any new content in 176days! That's dispite me pinging them when I made new posts for the first few weeks of blogging. After that I gave up and moved on to other pinging services that seem to actually work! My favorites being Blog flux and ping-goat, I do alternate between each of these, but they ping all the major search engines and give a report over each ping and whether it was successful. Funny thing is, both respond saying that the ping to technorati was successful, yet they don't seem to update!
