No worries.
Maybe im making it more complicated then it is.
Each page just has some sharing buttons, when someone shares the page using one of these buttons social signal is generated, end of, happy days.
So the type of thing you could do which is similar to your page is the social sharing box at bottom/left - http://blog.kissmetrics.com/
Penalties don't even come into this so forget that worry.
But do you get what I mean from that example link?
