3 Social bookmarking solutions for research Collaboration compared

A social bookmarking fan compared recently 3 of the great free tools: Zotero, Connotea (Nature) and 2Collab (Elsevier). 

2Collab “is in many ways the best of the three“.
“The emphasis on collaboration makes 2collab more than just a place to store, categorize and manage your scholarly bookmarks. It is also easy to discover new research material, share and identify quality information and mine the collective wisdom of experts. You can also form discussions in private groups or openly with the wider scientific community.
You can add references easily by using a bookmarklet in your browser or importing them from your browser, another social bookmarking or bibliographical site (Scopus).
You can export references in different format. In addition, your library can be shared online with groups of colleagues.
