Programmer here. HTML 5 is dominated by scripting, which I think we will regret. Marked up data is easily manipulated and repurposed, but arbitrary code has very few uses other than executing it, which is mostly why script-heavy documents tend to be trainwrecks in accessibility and search. And I desperately hope there's going to be a more usable and declarative schema for HTML 5 than "anything is valid if you carry out this long parsing procedure and it says it's valid".
