Ok, I don't use these things myself much so I'm a little unclear what exactly the Social Networks feature does. I've read the doc on it, and it says how to do it, but I'm still not quite sure what the end result will be. What will it enable users to do? Or me as the webmaster for that matter? Do I need a Facebook and/or Twitter account first to make use of these (I'm mostly interested in these two)? Will they add exposure for my site at these places?
Thanks for any help.
