Clearly forumites are like molecules.....
There london forumites are like the molecules in a hot dense liquid (eg a cup of tea). They are forever bumping into ieach other in a brownian motion sort of way.
Then there are the forumites in many other parts of the country. They are like the molecules in the near vacuum of deep space. They can travel for years without seeing another molecule. Occaisoinally there is an "event" like a micro miniature black hole, drawing forumites in with a pull of gravity, using the inverse square law of distance to the event. They cluster together for a short time - reacting according to their molecular characteristics - then spin off into space again and travel their lonely way through the vast emptyness.
