https://www.ohloh.net/p/sage

has a nice code analysis including distinction between comments & code. It 
says we had in September 2011:

450,000 lines of code
534,000 lines of comments
212,000 blank lines.

There's also a more detailed breakdown of languages etc. at

and top developers in terms of commits (not LOC), i.e., it favours early 
adopters when getting a patch is was much quicker/simpler:

me (3%), Jeroen Demeyer (1%). 

There's also a breakdown for the last 12 months:
