Tag Clouds dont work for me. Reasons-
1 A tag cloud is all visual clutter, no information (or wisdom).
2 Only big text shows clearly, what about all others? Are the small ones only there to be ignored?
3 No one except the creator knows how the tags are interlinked.
4 You cant expect to find what you are looking for by clicking on a tag (which unfortunately is their purpose).
Seems to me tags are very “individualistic” in nature and does not help for a visitor or as a community feature.
Examples of tags- gmail labels, del.icio.us tags, google notbook tags, imdb keywords
If only tag clouds could look something like this..
