Thing seventeen was nearly the undoing of me. I don't know why it was so difficult...once I broke through it was quite simple (aside from Google Reader not wanting to accept my RSS feed). These are very handy tools for the researcher/student. I can see the ability to find sources and send them to co-workers would be a very effective way to share info. The rss feed never came through Google Reader but I was able to a desktop rss reader (NetNewsWire). I plan on visiting these sites again in the future...a handy resource for the student or just the curious.
