While searching Technorati, I noticed that its tagging mechanism for the tag "http" brings up the following links, none of which are related to "http". The only thing relevant to http is that all these posts have links starting with "http://…", as indicated by the highlighted "http".

While it can be argued that this is a bug in Technorati’s feed parsing engine, there is a larger question here. If I really want to search for a keyword, I would use a typical search engine to find relevant content. Tagging, on the other hand, lets users mark content based on how they see it. The question is, should tagging me left to humans?
