"""I hope this made things a bit more clear.""" Yeah, much clearer. Here are my remarks: """Searching in shared posts in Google+ is one of the key features that Google+ has over Facebook and other social networks since it will let you simply search for "that interesting site my friend shared with me last month" instead of going through his posts manually.""" Maybe, but that would be trivial for Facebook to add. It's not like full-text search is rocket technology. And in this domain, PageRank is not even needed. """Google+ is more natural because of it's Circle system. You don't broadcast all your interesting findings to everyone you know, you tell it to the select group of people who might be interested, just like in real-life. """ Yeah, that's nice. But does it bother people using Facebook? I don't see it. Also Facebook added some similar features lately. """Then where will Siri get the results? Siri can't pull them out of thin air, they have to come out of a search engine and if Apple values the "magical" experience of it's users then they should use Google.""" Not necessarily. There are better sources than Google for a lot of stuff Siri caters for. For example, Siri already uses Wolfram Alpha for math, stock, general information related searches. Apple could provide its own dictionary searches, wikipedia searches, it's own map data for location searches, use the iTunes DB for music and lyrics searches, IMDB for movie times and movie/actor info, Amazon et al for shopping, travelocity of something for airplane tickets, etc covering a lot of ground query-wise. And they could also switch to Bing in a heartbeat. You get the idea. """But I think that is a bad move, since Apple would then be inventing the wheel again, only to disconnect themselves from Google maps.""" No, they won't invent the wheel, they bought a company that has already invented and made one. And it only makes sense to disconnected from Google Maps, a service by a competitor mobile OS vendor, that could even cut them off of it altogether when he wishes.
