Is it true that the major disadvantage with a subject directory is that users have difficulty deciding which categories to choose as they work through the menus of links presented?

This complexity can lead to confusion and frustration, as users may find it challenging to identify the most relevant category for their search. Consequently, this can hinder the efficiency of finding specific information compared to more straightforward search engines.
