No, we can not. Many of us use this function and shouldn't be considered just cause the tin foil is getting a bit tight on a few people. If the NSA concerns you that much, then maybe you should reconsider the activities you choose to take part in. If your law abiding, then NSA shouldn't be a concern.
I assume you don't share private stuff with other people online you don't really know. Stuff about your family, about your bank account, about health problems you might have or have had in the past, sexual preferences, whether your current relationships are working well or not, maybe about (previous) sexual or psychological diseases for you or with the people you know. To name some random subjects.
Most likely you would keep most of this stuff rather private. You'd definitely not broadcast this to everyone you meet, especially online. There's a reason for that. And a good one at that. But I doubt it is because you're a terrorist during the nighttime and fear the FBI will get you if you tell others about the subjects mentioned before. I think so at least, otherwise you definitely would be surprising me.
The point is: "if you didn't do anything wrong, you shouldn't care whether people check on everything you do" is a crappy situation to be in. It also promotes abuse of power. Or increasing usage of that power. For example, I think most people would be okay with checking in on terrorists or pedophiles. I mean, we all hate them anyway. Murders are probably fine too. But then, what comes next? Thieves, perhaps. Okay, cool. And then? Piracy? Cheating on a math test in school? Doing drugs? Lying to your mother about a party? Having a different political opinion than the ones that rule the country? It's a slippery slope, and before you know it, you could suddenly be next. And by that point, there's no way back. It wouldn't be the first time in history that these kind of things happen.
Now, this is not too likely to happen in America, or Europe, especially not in the short run. On the other hand, a lot of big companies and governments want as much information as they can get. This all ready happens, in increasingly big amounts. Those adds google serve you are not so specific without reason. Between google services, they probably know more about you and your preferences, than many people you know in real life do.
Should we all start panicking? Nah. Is it good to be informed about this stuff and possibly discuss what's going on, where it could lead to and where it's leading right now...? I think so, yes. Knowing is usually better than not knowing, and these kind of discussions can be quite interesting. And calling everyone who cares about privacy and its limits "tin foils" is a bit of an insulting way to talk.
It's been more then 2 years most of the ISP companies are already helping government with that task as well .
