Why not everything is connected

My biggest opposition to statements like "everything is connected" is that they mean nothing. Actually, they have a potential to mean a lot, but while they don't, I just ignore it. (And the best way of ignoring something is writing a text about it, everybody knows.)

If everything is connected, how could I use that information? Would I read the position of the stars on the future just by looking at old umbrellas? Would I know the color of other people's underwear by examining a very colorful shell? Would I have luck on the casino just because, in the same day, a plane had to land in a different airport at the same city? Someone who knows what connected means please don't hesitate in clarify me. While it is just some abstract connection, that we are connected to each other and to the Mother Nature, I can't take it seriously.
