This is Ryan Damico from crocodoc (YC Winter 2010), an online app for marking up and reviewing PDF files (as well as other document types). One of the reasons we started crocodoc is that Adobe's tools for working with PDF files (including Reader) are way behind the times (e.g. slow, desktop based, difficult to collaborate).
That said, crocodoc is still early in development and has some kinks of its own we're working on, but we think there's a lot of room for innovation in this space. Would love to hear any feedback!
