The pages make other parts of Facebook more useful. Before these pages, you had to Google people's interests to find out what they were if you didn't already know, and if the results were ambiguous, you'd have to do something crazy like actually ask the person directly. Now interests are well-defined. Sure, the solution they picked gives them ulterior SEO benefits, but to compare it to Mahalo and suggest that it's useless doesn't make any sense.
