Having shared the links to two 'knowledge sharing networks' I am now have a dilemma. Which shall I use? I don't want to have to maintain lots of collections. I already use Zotero for my own resources, but that is incomplete.I have links in documents and bookmarked we content which have never made it into my Zotero collection.
So now I am wondering whether to invest my time in Diigo, Mendeley, something else or stick with Zotero (supported by my employing institution) and my Blog entries.
