Personalization is the new magic buzzword of application development. To make the complexity of today’s application functionalities and information spaces ”digestible”, customization has become the new go-to technique. But while those technologies aim to ease the consumption of media for their users, they suffer from the same problematic: in the age of Big Data, applications have to cope with a conundrum of heterogeneous information sources that have to be perceived, processed and interpreted. Researchers tend to aim for a maximum degree of integration to create the perfect, all-embracing personalization. The results are wide-range, but overly complex systems that suffer from issues in performance and scalability. Starting from our own, similar experience, we argue for a

We demonstrate the concern based on an application developed in our laboratory: a system that profiles web users based on their browsing history, with the goal of personalizing digital advertisements.
