So I have been using Usenet for a while now but there are something I still don't understand:
1. What makes a post incomplete in the first place? To transfer files, I am pretty sure they use TCP protocol, isn't TCP supposed to deliver file in a pristine condition?
2. How can usenet providers make profit if they charge such as low price? I downloaded 300 GB plus last month, and paid $11 to astraweb. Usually, other hosting company like godaddy.com charge a fortune for 100 GB per month, (they say their unlimited but that's a lie).
