This should be 'htmlblock'.

Yes, these should be htmblock and textblock respectively.

Charset sounds important.  I'm not sure about content-type; it seems
like we could just have separate cluetypes for all the various content
types.

The issue that you've zeroed in on is that we're conflating the content
type and the content description in the cluetype.

Well the current solution to this is to use textblock and htmlblock
cluetypes.  I'll add htmlblock to cluetypes.txt.

That is what the relevance attribute is for, yes.

I think once we get the dashboard continuously running on our desktops,
we can start tuning relevance and match quality.
