I like piwik and sendy analytics, but for me the main issue should be allowing a creator to know someone cared and to improve content for said audience, I use Ghostery too and whitelist where I feel happy, but this is purely on the basis that I want to tell content creator I've visited and if I sign up to a sendy email then I would like sender to be able to know if I looked at email and what content I like (aka click) After that it all becomes bad news normally .
I don't think I give up privacy by showing my support via an open or a visit, but most of the web is not like that so I block.
For example I see Aral has worked hard to make sendy more private but I'd like you to know I opened email and I'd like you to know what I clicked as this will help build a better newsletter, now do you need to know it was me?... Maybe not but then again gender might play a role, maybe you want to increase the number of female readers, some stats might help... Sure they become pigeon holes, and there are better ways to do this but... It gets complicated. Something like GoldieBlox was not made on a whim they talked to people and thus via permission first they gained insight to encourage Girl Engineers. Many things to consider.
