PDF as an Online Document Format 
In January (2000), I asked about TechWhirlers' experiences as users of PDF documents online. The specific questions were: Do you notice a difference between reading PDF online and reading HTML online? Do you have a preference either way? If so, which one? Here's the summary or responses and a synopsis of further information I've been tracking down. I'm sorry it's taken so long: like many an unplanned project it got way out of hand. I've tried to restrict this message to issues of interest to the list; if I've failed please accept my apologies.
