Hey! Reading through the quickstart now, looks really interesting. However, it seems like something has happened with the PDF to make most of the text not searchable, at least using my reader (Foxit). The headings are searchable (Ctrl-F "Wall" gets a few results, for instance) as well as some of the italicized text, but the bulk of the document is not. The document is still relatively short, so it's not much of a problem, but I figured I should let you know.
Edit: This seems to be specifically Quickstart.pdf - the Spreads version seems to parse just fine.
