I prefer to download PDFs for offline reading. My motivation is as much because I prefer Apple Preview to web browsers as for flexibility when traveling. Could you expose self-hosted links for alternate PDF (especially source) content?
This is a nice suggestion. We're hoping to include the Scala Language Specification in both HTML and PDF at some point- if it turns out that it's straightforward to generate PDFs from our other source files, we'll look into generating PDFs for other important articles as well.
Alternatively, we've yet to provide a nice printer-friendly view of the articles as well, which we could set up to output as nice PDFs.
Thanks for the suggestion- we'll see what we can do :)
This would be helpful to me as well. Things in the "Guides and Overview" section seem like ideal candidates for PDFification. I wanted to download the Introduction to Collections doc to read on my Kindle, but could not. Even providing a "Everything on one Page" would be hugely helpful, because then I could save it in Instapaper, or print it to PDF myself.
