My knowledge concerning tags amounts to the fact that tags can be attached
to messages (either within the message or separately at the bottom of the
message) to allow your content to become searchable using those tags
(social media sites as well as ubiquitous for their use, for instance
you can enter
#Magento on Facebook or
[Magento] on Stack Overflow in
the search box to display all posts related to such tag).
This is all I know about tags.
Now I would like to know how the Magento "My Tags" feature works (this feature is visible under "MY ACCOUNT" in the customer dashboard). What kind of media can be tagged in Magento? Or do I have the wrong idea? Why would each customer have their own set of tags, rather than the tags being globally searchable and accessible to all magento customers. Is it the customer reviews that the customers themselves can tag and what is the syntax of a tag in Magento?
Thanks for the clarification.
