[Edu-sig] meaning of +1

[Brian Blais]

Hello,

I am not asking an existential question about the meaning of the integer set, but 
rather what it means when someone writes in an email on this list, something like:

+1

I've never seen this on any other list (other than python lists).  Is this just a 
short hand for "good comment", or is there a deeper meaning or purpose?


thanks,


			bb
