Checking out yolink help pages

Just checked out yolink to use with diigo and with Google docs. It's an amazing application. Never thought search could be so much fun and intuitive. It gets closer to my dreams of doing qualitative data analysis using only web based apps.
Defintely worth investing time in. One wonders if there may be a pubmed gadget that makes searching easier.
