I felt the dichotomy wasn't between browsing and query-building but browsing and analyzing something something one has found. The transition in tabulator comes when you have browsed a and found and selected a subgraph and then you ask for a view of all similar subgraphs out there in the web, with the button we now call 'find all'. (As you have to first select a set of fields, it isn't intuitive for the newbie. -- I like your "what on earth just happened?" popups! Maybe it needs one of those.) The generation of the query is query by example. It is similar, but freebase parallax allows you to follow any relationship which presidents have, rather than picking a specific president as an example and then generalizing. This avoids problems of finding an example which uncharacteristically doesn't have the direction you want.
