Even if you aren't particularly interested in Satoshi themselves, it contains several discussions about features, and proposed changes which I find particularly interesting considering where we are today.
Its worth looking at who's influenced Bitcoin in the early days, and who remains involved. A lot of accounts aren't recognized accounts today.
I think some of the most fascinating posts from Satoshi's account aren't just technical, but probably actually the ones where Satoshi expresses a personal view. For me reading his opinions about Wikileaks were a surprise. It seems that the new attention Bitcoin received in late 2010 may have been a reason for his disappearance.
The project needs to grow gradually so the software can be strengthened along the way.
I make this appeal to WikiLeaks not to try to use Bitcoin. Bitcoin is a small beta community in its infancy. You would not stand to get more than pocket change, and the heat you would bring would likely destroy us at this stage.
Interestingly, it suggests that Satoshi did not expect the level of popularity that Bitcoin has reached, claiming that Wikileaks would 'not stand to get more than pocket change', even though just one Bitcoin, at the time worth practically nothing, is now worth tens of thousands of dollars. He even described the new Bitcoin users coming after the PCWorld article about Wikileaks a 'swarm'.
