Upcoming Webcast on Feb 16th: Building Toronto.com with ASP.NET 2.0
I just saw on John's blog that there is an upcoming web-cast by the folks who built and launched http://www.toronto.com in October of last year (pre RTM) describing the architecture of the site and their experiences.
You can register for the free web-cast here. You can also read the case-study that was produced about Toronto.com here.
Hope this helps,
Scott
