i've always thought of are.na as a labryinth, waiting to be explored. if you're in, it's hard to get out.
Although maybe a labyrinth isn't the right comparison. It's much more complex. Like a rabbithole.
One tunnel (channel) has many entrances and intersections. Intersections which lead you to more tunnels, which then lead you to even more tunnels. The tunnels are lined with information, art, research, thoughts and sometimes pretty personal notes.
The more one explores, the more the amount of connected information grows..
