I'm a skeptic too, but when things work they work! :) There's a difference between being cautious, trying things out before blindly accepting them, and being *closed minded!* The former lets you get someplace new, the second? you stay where you are forever! argh!!!
But timing is so personal and so important I don't evangelize things like this, I leave it up to other people's timing to choose to do so or not as they will. :) I just bring it up when asked, and even then I don't persuade, only educate. :)
