I just got back from the Open-Source Convention up in Monterey, otherwise 
known as OSCON 2000. It was incredibly fun and there was a huge amount of 
enthusiasm for all the amazing projects taking place. There was a huge amount 
of talk about Perl and Python, but I didn't hear much about Ruby. Since the 
conference was sponsored by O'Reilly Books, I decided to ask them if they had 
any plans on publishing a Ruby book. I've attached their reply below. I'm 
anxious to get my hands on a good Ruby book! I know Dave and Andy are working 
hard on one and I'm really looking forward to buying a copy.
