Some quick facts I see from these numbers:

- 441 commits in three months! I don't believe we had this much before in
  other developments cycles (Congrats for us!).

- If my math is correct, the rate between review + tests + signoffs (386 + 31
  + 554) and commits made (441) is 2.2. In short, that's the average number of
  reviews made per patch that got commit.

- the delta (302) between lines added and removed are small. I think this is
  perfectly understandable given the amount of clean-up we had (MAXSCREENS
  removal, *alloc, PCI stuff, etc) in 1.9 development against the features
  added.

- 39% of changeset represents contributors not affiliated with any company
  (gitdm -u). Worth to note that Jamey and Mikhail made a huge amount of
  contribution and I counted as "not affiliated" - probably wrong.
  
  Maybe we can say that X development could survive in some way even not
  having any company directly contributing there. 

- Intel, Nokia, Red Hat, Oracle and Apple are on the top five. Other known
  companies that care about X and desktop like Google, Canonical and etc are
  far from those on the amount of contribution.

- what else?


Well, that are just some facts that I got quickly running gitdm here. I don't
think that only the xserver represents all graphics development under X.Org
community. It's just a portion of it and we would have to include DRI, Mesa,
drivers, etc to get a more accurate analysis. 

Anyway, as I said already, I'm particularly very excited about the development
and how fast it is going. Just take a look in the growth of mails changed in
xorg-devel which proofs it: June -> 1261, May-> 1432, April -> 1157 while the
months before were half or less roughly.

If I have more motivation I'll try to get some stats comparing different
versions of the server development and maybe other modules. Also, if you are
interested on different kind of statistics I can run more. Suggestions are
very welcome and appreciated (for instance fixing contributor <-> company)!


Cheers,

[0] On the top of the Jonathan's tree I applied some patches concerning X.Org.
I'm cc-ing him also who might be interested to fetch it:
