My plan has always been:
* keep making tags lowercase
* keep quoting attribute values
* keep closing tags after I open them (and properly nesting tags)
* keep using the closing slash for standalone tags
* keep calling it text/html (mime type)
* keep using UTF-8 encoded Unicode by default
* keep not using xml namespaces
* keep forgetting to use the DOCTYPE declaration
* and start carefully using some of the neat new tags in html5
