If you try to value gold objectively (its industrial and possibly jewelry use), its price should be significantly lower than what it is today. Speculation and paranoia have driven its price to amazing heights. A value investor can't touch gold with a 10 foot pole.
I know Hacker News has its share of gold bugs and libertarian survivalists preparing for the fall of the US government. My only recommendation for you all is to remember to leave a map to your buried gold in case you die unexpectedly.
For those who don't think the fall of civilization will come within their lifetime (which I hope is the majority of you), trying to match the market with a heavy diversification of stocks/ETFs and bonds (notably US government bonds), a long time horizon and a yearly re-balancing is probably a better bet.
