Just a quick hi if you came across this blog from an article on the CNN Money website of all places. They feature a number of websites that "offer information and diversions that can ease the pain of your daily slog." and for some inexplicable reason spend the end of the article on this blog - "Across the pond, Webmaster Annie Mole operates "Going Underground", a daily blog on the London Underground where posters ponder such mysteries as how seven stops and one change can be faster than two stops and one change."
Quite nice being the only site about the Tube on it.
In the article I really liked the site on carpooling (or slugging) etiquette as it was very similar to our tube etiquette in a number of ways. Slugs do not talk, they don't use their mobile phones for more than a short while, any time they do talk religion and politics are avoided and there's no smoking or eating by the driver or slug.
Perhaps people on really long Tube journeys should start tubepooling (or slogging). You could agree to actually properly share the journey with the people who get in the tube with you everyday (you must see people who get on your carriage every day). So you could share copies of Metro or other newspapers, take turns at using a seat if there's only one available, or even sit on each other's laps.
