There’s an interesting blurb over at the Campus Technology blog about a research tool called iBreadcrumbs.com (does EVERYTHING have to have an ‘i’ in front of it nowadays? Look what you have wrought upon us iApple!).
It looks like what iBreadcrumbs does is sits in your Firefox browser and lets you store (and share) your research trail. I did a quick one today, go ahead and see what I’m researching right now.
