@Green Witch,
GW, I remember when my best friend used to brag about how much he was worth on paper during the tech boom, but said nothing after the bust. I believe it's just human nature to brag when people have done well in the market, and fall silent when they've lost a bundle.
The best strategy are those that have been preached and practiced for the long term; diversify, don't try to time the market, buy low and sell high, and keep a ratio between bonds and equities depending on one's age. Simple, but many don't heed.
