To boost numbers on this site I think we could possibly share it on our facebook? I know this depends on the religious affiliations of family and friends on facebook. But there is one good trick, you can customize who sees that particular post, and exclude certain people who might take offence to the link.
The promote page has the direct links for social media
I was seeing ads for this site constantly on FB so they seem to be already targeting FB users. I belong to some Atheist groups on FB so I'm guessing that's why.
