Why doesn't Linux need defragmenting?

The way the blog phrases it, it sounds like there's nothing inherent in
FAT versus ext2 that would promote or reduce fragmentation; rather, it all
has to do with the free-space allocation algorithm.

Windows tries to put all files as close to the start of the hard drive as it
can, thus it constantly fragments files when they grow larger and there's no
free space available.
Linux scatters files all over the disk so there's plenty of free space if
the file's size changes. It also re-arranges files on-the-fly, since it has
plenty of empty space to shuffle around.

I'm actually interested in a more detailed analysis, as I have the
feeling the author skimmed over a lot of details, and this is a topic I
don't have a strong background in.
