There is nothing wrong with writing the odd post, but crudely repeated posts over multiple accounts doesn't wash or endear.

There was an error rendering this rich post.
I've always been skeptical on any posts relating to this soical login. It seems like there is one person from loginradius that is making duplicate accounts all over the place trying to promote their own stuff. Most posts are from users with 1 comment either saying "Have you tried this plugin" or "Where can I download this awesome plugin". Vanilla already has this social media stuff built in. Other than that, it seems like it is a wrapper around OpenID.
