I'd like to say few things about why Loforo isn't a clone of soup.io.
Loforo seems to be closer to Tumblr than to soup.io actually.
This will be a rant about User eXperience.
Soup.io:
The very basis of the soup.io phenomenon is the continuity of focus.
You are always in the same space: On a timeline. Either /everyone or /friends or /fof or a particular user.
You scroll the timeline and no action except explicitely clicking on a permalink takes you away.
