There is no moral to this post – I just want to share some cool links and whitepapers.
A little while ago “some people” got slightly annoyed that Google has started offering encrypted search. What this means to you is that your analytics software have no way of seeing where the visitors are coming from, if they used the encrypted search.
In related news Google has just released a browser plugin that let people out out of being tracked by Google Analytics – This didn’t go over well with “those people” either.
But fear not!
