Why doesn't my browser compile and store my viewing habits, then construct searches for me? Searches which Google then executes? Centralized services have built personalization systems in which they operate the personalization algorithms. I don't have a problem with that, per se, except in that their interests (profit) and user interests (effectiveness) are only partially aligned. The biggest reason, as near as I can tell, these system architectures were built is that control of personalization algorithms means (1) a means and reason to collect and retain data on users (that can be used for targeted advertisement) & (2) a means to execute targeted advertisement (via insertion into "recommended" content). It's likely the only way these services are possible at the "free" price point. But it's disingenuous to suggest that they're the only model by which personalization could be realized.
