Bookmarking

Okay, so this bookmarking thing with Connotea, Zotero, and Delicious have become more of a hinderance for me than a help. I am not sure if I am doing these things right and I definitely still don't understand the whole export/import thing at all. I am not sure if I am suppose to be exporting/importing on Zotero, Connotea or Delicious or none of them. I have tried using the sslvpn.pitt.edu to search databases, but I have no idea how to get my finds into Connotea, Zotero or Delicious. Do I need to export somehow? I don't feel that I should have been on the computer all day trying to figure this out. When I met with John the other day, he made this all look really easy and now that I am trying to do this, it's not. What shall I do??
