I've realised that people are not really using the various content share options that are available on my network. To try and encourage people to share I've added a background image to the share functions at the bottom of blogs, videos etc:
Click image to see it in action:
Just add and adapt this css to your appearance (in classic mode):
/* Broadcast options in left panel */
-moz-background-size: auto auto;
background-image: url(IMAGE URL);
background-position: 0 0;
I'll see if this encourages people to share!
