I know it's not really auction related, but since eBay owns such a large part of Craig's List, I'll stretch it to say it's auction related. :)
So here's the deal... earlier this month, a company called Deep Space Communications Network beamed the worlds first commercial transmission of a web site into outer space.
What was the transmission exactly? About 125,000 random postings from craigslist.org of course! So now if aliens need to find a roommate or are looking for a used saxophone, they know where to get it.
