Yesterday I decided to join Rob Conery in disconnecting my hand from my mouse for 'International Mouse Freedom Day'. What's more, this was a full real-life day at work rather than just a little experiment at home. The idea was that ditching the mouse and embracing the keyboard would speed everything up, make me more efficient and probably save the world.

The use of tagging on websites seems to be something which has gradually become mainstream in recent years, particularly since the advent of 'web 2.0', where it became very widely used. I thought I'd explore this phenomenon, as well as discussing the implications, advantages and disadvantages of tagging and tag clouds and exploring how various different sites have approached it.
