My posts still appear in the del.icio.us results sidebar on the Technorati tag search results page, but they're not making it into the main list, which sort of makes the 2-birds-with-one-stone category method a waste of time.
I have checked the tag syntax (url and rel="tag" &c) & it seems to be the same as that described on the technorati tag help page, so who knows?
Update: The tags must be OK, because our German friends at Taggling can see them just fine... (see their recent results for Harry-Potter.)
