So they've renamed HTMLDB. To be honest, I never liked the HTMLDB name. It sounds too much like a mumble. Old-time readers of AskTom will recall him referring to it as Project Marvel, which sounds much better.
Application Express is also good, but takes too long to type, so I've put a poll together (thanks Eddie for the pointer to dpolls) on an abbreviation for it. Feel free to add any other suggestions.
