Mostly looks good.  At the very end of the section on noise, redundancy 
and information theory I think I made a comment that the scribe missed. If 
there's no dissent, I'd like it recorded:

After the existing entry:

Chris: redundancy helps succesful conveyance of information accurately. 
Hence the need for surrounding context when using a URI to transfer 
information

Noah:
True, but I wanted to clarify that I wasn't referring to lossy channels or 
redundancy when I suggested that information theory could help us.  Though 
I'm not expert in Info. Theory, my understanding is that it gives a 
definition of "pure information" (my term, not Shannon's--I don't have his 
writing here=) that is essentially what you are TRYING to communicate 
through the channel.   So, by analogy, we need not have redundancy in a 
temperature value or the words in a poem to say that they are 
"information".  We may need redundancy to communicate them with some 
predictable probability of success through a noisy channel.  HTTP needs 
redundancy on the wire, the info resource definition as information does 
not involve redundancy IMO.

I've elaborated a bit but I think this was the spirit of my comment. Might 
this be added to the official minutes?  Thank you!
