If you're reading this from work, then you're lucky enough not to have an employer stupid enough to use the websense filter. As of this morning, whatfettle is categorised as 'an inappropriate message board or club'. They also apparently block flickr because it contains 'pornography', which rather misses the point. Of course you'd expect any company whose stock in trade is 'innovation' or 'communication' to never consider enlisting a Ministry of Truth to keep its staff ignorant. But you'd be wrong.
