Del.icio.us

I heard about this site some time ago but I never followed through with finding out more about it. Using Del.icio.us paid off almost immediately. By exploring Del.icio.us's search function I found the wiki Librarian Chick. This site had good links to other helpful sites, many of them Web 2.0 applications. The application of making your bookmarks portable by using this web based service was the second service I found very useful. This can be particularly useful when doing job rotations.
