I downloaded all of the PDFs, and it took a very long time, even on my
fast connection at work. My guess is that Wolfram gives these
downloads less bandwidth compared to, for example, downloading
software, or the curated data. But I would say that's all right.

The largest of the files is "Visualization and graphics", which comes
at almost 140MB. I opened it in Acrobat (Professional version), and
simply out of curiosity removed all the Metadata and hidden
information in the pdf (You can do this under the Menu item "Document
> Examine Document...", at least under Windows). After doing this, and
saving the file, the size was reduced to less than 30 MB, just a bit
over one fifth of the original! On first visual inspection, the two
versions appear to be identical.

This particular file contains lots of graphics, so the reduction in
size might not be as large in other files, I didn't try. But anyways,
this begs the question: did I remove ANY functionality by doing this?
If not, it would be much nicer if Wolfram could place PDFs of reduced
size for download on their website.
