I hear the concern about dependence on guides, and it is entirely valid to note the change in habits with the internet.
However, considering that they are not an essential component of the initial choice seems to ignore their broader role, even if it evolves.
For many, a guide is a first source of inspiration and structure for fundamental questions, well before looking at prices.
For example, for an event, one does not start with the caterer, but with the type of event one wants to create, and a guide can help define this vision.
