You might find Zotero (zotero.org) of interest. It's a bibliographic
management application. Currently it runs as a plug-in to Firefox but an
alpha standalone version has just come out. You can attach and store
PDFs. You can't annotate them directly although you can store notes
about them (or any other reference in your library). It can store
screenshots of web sites, too. And, of course, once you have stored your
references you can add them as automatically formatted citations and
bibliographies to Word or Open Office docs.
It has some social networking capabilities; you can create groups to
build and share libraries or you can create a library of references that
is public. (ex: http://www.zotero.org/groups/digital_humanities_education)
It is supported by the UVM Libraries
