This is a good read, but I'm a bit concerned by his product Tamboo[1], which lets site owners track exactly what their users do on their sites. I was looking at competitors and found Smartlook[2], whose website asks "Is this super-awesome service even legal?" A better question might be, "is it ethical?" and generally when you're asking is it legal the answer to that question is no.

In my opinion, the legal aspect is unclear too. In case of brick and mortar stores, AFAIK, most jurisdictions require a noticeable sign revealing surveillance/videotaping. The law hasn't quite caught up online though.

Regardless, I'd say it's ethical if they clearly tell users they're being watched. I bet no one would use the service if it was required.

Yeah, I'm not totally against the idea, but I know a lot of people have concerns around privacy online and how data about them is collected. I agree that you should let your users know you're tracking them in this way if you use something like this.

I have a hard time with hit myself. Mixpanel is another competitor here and, when properly integrated, it can show some pretty shocking details about app usage. Great for optimization, poor for user privacy.
