@Gavin
out of curiosity i ask myself how many ppl would be subscribed at that @metzdowd.com mailinglist ? can someone tell ?
Is Satoshi only talking to himself to have a reference of early publishing ?
whats a metzdowd ?
It's a public mailing list so any number of people could had been reading without being subscribed or posting. Only the list admin would know for sure how many subscribers the list actually has. Given that it appears to be active since 2001 until late 2010, I don't think Satoshi could had been talking only to himself in 2009.
