Oggetto: Re: [Tails-ux] Report on Piwik prototype
Once upon a time, webmasters had the same problem with AOL's proxy.
Millions of people had the same IP. The workaround was to count a new
user session every time the same IP was inactive for a few minutes.

One problem with IPs now is that the EU privacy rules seem to require
not identifying users to websites without their opting in for that.

IMO, counting people is overrated. The better questions are around why
people come and what they ask for and do. User vocabulary. Page views.
Search terms. You can learn a lot about those things without needing to
identify individuals.
