For me, I just want to use their apps as tools. I never wanted a Google experience. As handy as it might be that Google knows all about me when I use these tools, I'd rather they not. I want that choice. I want my search results to be less catered to what has been determined to be my tastes. The privacy calamity that has engulfed us all aside, I would use equivalent services in a heartbeat if they didn't require such personal integration.
Same. I use gmail, I like drive... but that's honestly about it. I have an Android phone, that I love, but I don't use Now, or any of that stuff. Hell I turn off GPS and tracking immediately after getting a new phone. I don't like Google apps knowing where I am. I don't comment on youtube or have a channel or anything, so I guess this Youtube/G+ thing doesn't really affect me.For me, I just want to use their apps as tools. I never wanted a Google experience.
You need to write more specific queries, like you did with search engines before Google. Personalization does have some advantages, being able to guess what you're really looking for being one of them. I don't find having to type a few extra words to be a big disadvantage.
