If you have multiple groups e.g. football, tennis, cycling, make up, hair, etc - you can do it the old way of having a category header e.g. Sports and Women etc but it can be a pain for a user to find their specific group.<p>What is the best site out there which allows the user to find what they want quickly but without the pain?<p>I'm thinking spotify has a nice way of finding a track and finding the relative album etc via tags but i'm wondering about any others as well...
Multiple groups of what? The question is vague, almost to the point of incomprehensibility.<p>Here's a model for you: Gmail. Gmail allows users to tag content (i.e., emails) with zero or more labels, and displays a list of labels. When the list gets too long, the user can decide which are always visible, and which are hidden by default. Clicking on a label shows all of the content tagged with that label.<p>Simultaneously, a built-in search feature allows users to find content by free-text searching (which is orthogonal to labels.)
