Social media for scientists
The following slidecast (that is, a slideshow including audio) is an excellent presentation by Mary Canady and William Gunn on social media for scientists. Topics covered: LinkedIn, Twitter, social bookmarking (delicious, citeulike, Mendeley), FriendFeed, science blogs.
If you are a scientist and you think social media is completely useless for you as a researcher... well, you are wrong and must watch this!
