Technical Note: Comment Engine Switch

NOTE: The comment engine is being replaced from the current engine to a new one in the coming hours/days due to a substantial jump in the pricing of the current engine -- and that in combination with the fact that I've never entirely liked how the new comment engine worked pretty much sealed its fate here.

Please bear with me as I transition this. There may be a period where no comments are available during the transition period and some comments may be lost once the transition is completed.

UPDATE 7:00PM: The new comment engine is now active, however, as you can see, at present the historical comments are not yet showing up. I am conferring with support to see how to resolve this so that the historical comments will be active.
