8. Don’t confuse tags with keywords
or full-text searching
Keywords are behind the scenes, tags are often
visibly aggregated for use and browsing
Keywords can not be hyper-linked
Keywords imply searching, tags imply linking
It’s more about connecting items rather than
categorizing them.

According to Wikipedia: A folksonomy is the practice and
method of collaboratively creating and managing tags to
annotate and categorize content. In contrast to traditional
subject indexing, metadata is generated not only by
experts but also by creators and consumers of the
content. Usually, freely chosen keywords are used
instead of a controlled vocabulary

vocabularies do.
Term ambiguity – words with multiple meanings
No synonym control.
Singular and plural forms create redundant headings
No guidelines for the use of compound headings,
punctuation, word order
No scope notes and no cross references
How does wrong information impact retrieval
Conflicting cultural norms
Sometimes authority counts
