Remember that a 2.0.x release has to work for "everybody" and that a
1.3.x version just has to "work for me".
If you really need a version that is more "advanced" than the last stable
release you might have to try a few experimental kernels.
The Linux effort is mostly spare time for lots of people. This has some
advantages and disadvantages over the commercial operating systems.
Pro: There are probably more programmer hours invested in Linux than
in any other OS.
Con: It has to remain "fun" and "do-able" for those that have to actually
do things.
Trust me, David, Linus and others are all reading this, and will be
more cautious next time when bugfixing a stable kerel.
