Now that I'm back using non-proprietary databases again, these links from Christa could prove extremely useful:

The on-demand webcasts on MSDN can be a bit of a pain to find, but they provide some really useful content. So I went ahead and made pages for the dev-focused SQL and Data webcasts to make it easier for folks to take advantage of this material. The permanent links to these pages are on the SQL and Data dev centers, respectively, in the Multimedia section on the main page. I'll be adding the appropriate support webcasts to these pages as well - look for that update in the next week or two.
