Well, you do know that the distribution of all of our users are:
	50% only contributed 1 patch
	25% contributed 2
	12% contributed 3
	6% contributed 4
and so on?

Our curve is leveling out much better now though.  For the whole 2.5
release, the top 30 people did over 80% of the work.  Now, the top 30
people are doing 30% of the work.

So it is getting much better, as long as we still continue to keep our
massive rate of change[1] that we have going, and huge number of
developers[2], we should be fine.

So this list doesn't necessarily mean anything is wrong, only that 50%
are one-time contributors.  And I think that shows we are easy to get a
change into our tree from just about anyone, not that we are driving
people away.

thanks,

[1] 7,000 lines added, 2,500 lines removed, 2,400 lines modified, per
day for all of the 2.6.25 release cycle.  That's insane.
[2] 2,598 unique developers from 2.6.20 to 2.6.25
