I'm not afraid of having parts of my information online in general. Having a website often needs an imprint with a big part of your data. It's more like the information only friends and family know of and which are way more important in many senses.

- phone - this is kind of ok, because phone spam is less common

- email - to prevent spam

- birthday - this one is quite critical, because here in germany it is a common way to verify authentication on phone calls by insurance companies

- job-details, contact relationships, etc.

I doubt that these are all in the public registry.
