Maggie's Investment Advice
Oh man, do I love getting my investment advice in the comments section of Maggie's Farm. It's Bretton Woods crossed with the Algonquin Roundtable around here.

If you huddle around our investment topic entries, a virtual hobo campfire, burning hyperinflated banknotes, appears in the comments. Everybody's nervously fingering their Mauser triggers and wondering what will happen if they're the first guy to fall asleep with a pocket full of Spanish Main money in their raggedy (but thank god, not leveraged or made in China) clothing. It's great fun.

And the comment that caught my eye was this:

Buy when the thought of buying makes you feel like throwing up and sell when everyone else is euphoric.

Sounds good to me...
