Via Kevin Burton via Niall Kennedy: you can now do Technorati searches on multiple tags using the Boolean "or," such that a search on "folksonomy or ethnoclassification" (has the latter term officially died? There are precisely zero posts with this Technorati tag) will return you all blog posts with either tag. This takes care of some of the ambivalence problems in tagging, but I'm going to echo the sentiments of Tech Crunch and say that the Boolean "and" operator would also be highly useful for generating uber-relevant search results.
