So... Technorati is borked beyond hope; well, it's not like we're paying for it.
But anyway - I was interested to read of an alternative on kottke.org - pubsub.com. I had a quick look, found it... somewhat counterintuitive to use, but as I needed to reccomend some ideas for tracking celeb mentions on the web, I pointed a colleague to it.
About ten minutes later she came over and said 'Think you better look at this...'
A search on 'The Queen' had turned up some beautifully lurid blowjob porn.
So... I'll be rethinking that strategy then.
It's an all-to-frequent problem with engineer designed products - they forget the editorial and social buffers they need to impliment to make a product useful, usable, and for that matter, safe for work.
