If so, and you're in higher ed, we want to hear about it for an upcoming presentation at the EDUCAUSE Learning Initiative conference. You can e-mail your anxieties about using Web 2.0 technologies in education directly to me at trillwing at gmail dot com.
In addition, if you find (or author) a relevant blog post or web page, we'd love for you to draw our attention to it by tagging it "eli08fear" in del.icio.us. Pages tagged thusly are being aggregated on the "Got Fear?" blog created by the talented Martha Burtis. You should definitely go check out "Got Fear?" for some interesting reading.
