The simplysecure.org domain uses Google Analytics which isn't disclosed on their privacy page (as required by Google Analytics' TOS). There is also a mixed-content warning because someone hard-coded an http:// link to the balloons image in the blog post on their https site. I went to email them and first looked for PGP keys (us pro-privacy & security people all use PGP, right?) and found none for the domain on any key servers.
I point all this out because it perfectly illustrates their point. Here are a group of smart people launching a great initiative with a beautiful and modern website, and they made some mistakes just like the rest of us do.
I've offered to help and recommended they switch to Piwik (and fix the http link). I hope others here on HN who care about security and privacy will also offer to help out. Some of this stuff is easy to fix and I think it's a great initiative.
