It is fascinating to watch WotC flounder with its digital strategy. I know tons of people that are desperate for a well bookmarked version of the PDF. I know tons of desperate people that would like an actual index.
I know tons of people that would throw money at WotC to release PDF versions of the actual books.
I know tons of people that are desperate for WotC to release a useful way of consuming their data so that 3rd party tools could be made.
I don't know anyone that was desperate for an HTML version of the basic rules.
