Actually, Michael Sweet invited me, but I don't have the time to attend.

The text in that PDF file has all been vectorized, which is a bad idea
for a couple of reasons: display performance (fonts are faster because
they can be cached), and the file is no longer searchable or indexable.
That said, the next release of Xpdf will have anti-aliasing for vector
graphics, which will at least make the file look better (though it can't
address the performance or text extraction issues).
