It does this on a global scale, but it seems like this should be doable on a personal scale. The opportunities aren't just to create a personal search engine, but also personal cross-cutting views or operations.
But what we seldom do is actually _do_ this, actually have personal entities that scan and learn. Even though it's not particularly hard. I can't quite decide why it's so hard... are we worried about what an entity might do? If it might go crazy? Or is it too hard to get any value from it?
@ianbicking I'm not sure what kind of UX you envision being frenetic, but I like the cross-domain concept. Actually, I like it enough to have been working on a computing platform with that as a foundational principle for probably ten years now (it's a pet project).
