Reading this I found out about talktoaliens.com. Want to send an email 1 to 3 light years into space to the aliens beyond? They'll do it for ya - for a price.
Apparently the folks behind CSXT, the group that flew the first amateur rocket into space last year, are giving these guys a hand in their little venture.
It's a great idea. If there are aliens out they might as well be bombarded with spam...
What happens if the Aliens misinterpret all the spam as an attack? They would desire bloody revenge against the merciless humans and the electronic messages... Now that would be a hilarious sci-fi short.
