Google has this new script where it allows webmasters to display 'matched content' and mixes it with adverts.
It is currently being trialed on the sidebar and at the bottom of each LC site.
As you can already tell, the pictures it uses are selected from the thread and often not sleek or even relevant to the content.
Still, it may be a way of enhancing navigation for some users and even make some money to support LongeCity initiatives.
Thoughts?
