Good job on the podium/lecturn distinction. It really shouldn’t be all that hard for those who make their living writing and/or speaking - but you almost never hear a TV talking head use it correctly.
Next project (with about the same current batting average): getting those same talking heads to understand that cement/concrete are not interchangeable (the former is a fine gray powder; the latter, a matrix of cement, water, sand, stone, and chemical additives).
Would be very difficult to skin your knee on cement.
