Verizon plans to link its tracking of customers' browsing with those same people's other Internet activities from other computers.

The description of how this will work is garbled; can anyone show me a technically clear explanation?

In any case, I think it is unacceptable for an ISP to track customers' browsing at all.

The article makes a bad surrender when it legitimizes the surveillance of Google and Yahoo on the grounds that they offer "cool [gratis] services". This is tantamount to accepting that we should all sell our privacy.
