Count the number of new “social networks” focused on providing some equivalent to a “Like” button for something other than the web in general. Count the number that require you to take a picture of it and share said picture. Count the number that focus on food, especially. Particularly count those with a focus on mobile phones, often with their primary interface being through a phone. Count the number that actually claim to be a “Like” button for the rest of the world.
Now count the number that don’t suck.
