Pulseaudio is awesome, for the reasons stated above. I use a lot of those functions.
Anyways, I'm happy to see Valve tackling some bugs. They certainly have a decent amount of talent there, so it would be wonderful if they started giving some attention to the FOSS video drivers.
John Carmack did this for Nvidia and ATI with their graphic drivers. Another benefit to have games on Linux, a lot of developers will find flaws.
Does everything have to devolve into a Pulseaudio rant with you people? Sheesh.
There have been tons of flamewars about X/Wayland (no network transparency? X epically sucking?)
systemd/upstart/etc. - init should be simple, red hat wants systemd to take over everything, ubuntu has NIH syndrome, etc.
filesystems - ZFS? BTRFS? ReiserFS?
schedulers - CFS vs BFS?
It's simply what linux users do - complain on user forums.
How exactly is this news? When someone reports a bug, we get an article? Seriously.... :-/
