Bookmarking Sites...

I can see that this could be an interesting method to get group consensus on 'good/relevant' sites for a defined user group...for those willing to participate, evaluate and post. Many of the comments I saw for some sites were just cut and pasted from the site. In some ways I feel like I am sorting through an old fashioned vertical file with a hodgepodge of materials being added by people...many things 'nice' but not highly relevant to what I'm looking for....
