Well, it's not exactly people that passed "Visual Basic for dummies" that is passing code up to Linus... I'd say the greatest sin I see is insanity like "I don't want to use KDE or Gnome because they take up 20-50MB of memory" and instead you:

7) Because your documentation sucks and noone knows what it really does, people copy-paste snippets that they know works. Spaghetti...
What I have found is that there are very few cases where you're doing it "right" and still get unacceptable performance. Usually there's some other problem, for example that you put something stupid inside a loop or the wrong loop and the compiler didn't save your ass. Been there, done that - the difference between O(n) and O(n^2) is pretty high when n=50000. But I'd take 5 lines of library-calling code over 100 lines of DIY code any day.
This kind of you see on both kinds of the stupid scale - those that are just so clueless they don't know what the library can do for them, and those that know it can and reject it because it's not "good enough". If so, get a patch upstream to the library and if you think that's too hard, the red blinkenlights should be on already.

A bit of code consolidation would be a brilliant thing to have happen.
There's so many projects out there re-inventing the wheel, and providing software that's almost useful, but is too broken to use on a daily basis.
Well, you might say most modern opensource projects (including Linux kernel) originate from reinventing the wheel. Reinventing the wheel is nice and fine if you're a brilliant software designer. Most just are not.

What most people that try to critizise KDE/Gnome for their bloated libraries is that those libs are there and in that size the moment any application uses it. 20-40 Megs may be much if you're just using it to play KMahjong, but on my Setup I have 20-30 apps using that. If all those apps used their own code for file-viewing and saving configs and all that I wouldn't have any space left.

That's why I like the way the LSB and QT and GTK have been going these last years: More and more functionality is going into the main libs and being standardized, thus getting more and more code shared. Sure it makes the main lib larger, but it shrinkens every other app using it.
And the way I understand it, Gallium isn't much different. That's why I'm preparing for a shitstorm on Phoronix, because initial releases of Gallium WILL be slower and buggier than doing everything seperate for every driver in Mesa. But it will be the right thing.
I guess those of us with both too much time on our hands and an extremely large amount of patience could start the testing and bug filing right now, with the softpipe.

Not sure about softpipe in general, but llvmpipe have instructions for building and running:
