Seems like Technorati has currently some problems with their servers. Yesterday the whole members section seemed to be broken. After a short e-mail someone from their support told me, that they have some problems with their database and that everything should work again now.
Well, now the search engine seems to be broken. At least the one handling Technorati tags. All I get are more or less empty listings like the one in the image.
Hopefully this will be fixed soon. I started really to like their services esp. the tagging one :-)
