I've been using del.ic.ious now for a few weeks, but I have bookmarked very little that is relevant to my other life as a GP. By searching for tags such as appendicitis, bts (for british thoracic society), and rosuvastatin I am establishing that there are few tagging clinicians out there.
It may be hard to convince medical students that social bookmarking will be relevant to their lives unless there are a few examples of early adopter clinicians using it well.
Are there clinicians out there using social bookmarking? I'd be interested to find you. And if there aren't, why not?
