Update 6-21-06: The question came up during the session about the differences between blogs and discussion forums. I'm not sure I answered it very well but mentioned I had some links in del.icio.us that I thought did a better job. Here they are in case you come back to look:
David Warlick tackles the issue.
Alan Levine continues the discussion.
Will picks up on it.
Also, since we ran out of time I really didn't get you going on RSS as much as I had hoped (much less del.icio.us). So I really hope that if you're at all interested, you take the time to look through all the links. It will take some time, but if you're interested you can probably learn in 3-4 hours what took me 9-12 months to learn. Then you'll really know enough about whether you want to pursue any of these tools or not.
Please feel free to contact me via email or the blog if you have more questions, suggestions or want to collaborate with any classes at Arapahoe. Also, if you have any feedback on the session itself, I even ran out of time to ask for that! I'd really like to know what worked, what didn't, and what could be improved (other than having another hour . . . or two . . .).
