For example (not relevant to our forum, but an example given on another forum) one forum is for doctors and has topics tagged with 'hand' when it's about hand issues or surgery. This is beneficial because if you search for "hand" it brings up many irrelevant threads.
Plus it's cool once a lot of threads have been tagged to go to the tag 'cloud' page here:http://styleforum.net/tags/
and the ones that are more frequently used get bigger, like the tagging in Flickr and some other sites that use a similar system.
