Oh I quite agree. The most the average person might practically benefit from such tools would probably involve using a setup as some kind of personal assistant (for the purposes of keeping organized, quick info lookups, reminders, etc etc.).

Unfortunately, it's also just inconvenient enough of a case scenario for most people to set up themselves (privately self-hosting) that this is the exact vector where a lot of people are going to end up exploited by data mining companies who provide (online) out of the box services.
