I signed up last year for emails from Casey Research, they
send out a monthly email called "conversations with Casey".
It's mostly on investing in gold and commodities, and diversifying
into other countries before the fit hits the shan.
Always interesting and they've been right so far, gold I bought last
year is up 30%...even more interesting this month they mentioned their
interest in scifi writing and linked to Speculator's Fiction
They included a link to an Isaac Asimov short story, from the 50's but
still excellent and it's called the Last Question.
You can go read it and access the MultiVax at the same site.
