Where is the \.blender folder?

That's why Hoikas loves the linux filesystem layout.

I must confess I don't see how putting the scripts folder in either Documents and Settings or Appdata makes any sense.
(Aimed at blender devs for actually including those options, not at people who chose that option )

Because it's user-specific files that are used by an application during runtime? There's no other good place to put them on Windows. That's what that section of the filesystem is for.
