There are many interesting conferences that are relevant to our class. You can "attend" many of them virtually on the Web. For example, there is a very complete Web site for Microsoft's recent MIX Conference. You can see the keynote talks and other sessions, read blogs and comments, see demos and video recaps, download beta software given to attendees, etc. (Atlas, Microsoft's new AJAX development tool was presented and is available for download).
Another excellent source of conference coverage is IT Conversations which posts audio recordings of the sessions at excellent conferences, most of which are relevant to CIS 471. You can listen to these on your PC or download them to an MP3 player for portable listening.
