What I learned.
From Zeldman, I learned that I might be able to use SMIL or other "caption authoring" tools to add changing text alongside a QuickTime movie. My client has been asking for this, and it sounds like we can use SMIL to add it to either QuickTime or RealPlayer movies. I also learned to use <img alt="" /> for spacer images and others with no meaning, vs. using <img alt=" " />. Zeldman has some great presentations that he gave us the URL to, I'll ask him if I can share with my readers.
From myself, I learned that Dreamweaver is a good weblog client, but it seems to keep putting line breaks in my paragraphs rather than wrapping the lines, which is annoying, and means I have to either (1) change a setting, or (2) remove them all manually. I just turned off under Preferences > Code Format and that seemed to help.
