I have just read a comment by someone that claims to understand how people read web pages: by 'scanning'. This is rubbish. They 'skim' -- meaning that they read quickly, glancingly, and skipping much material that appears to be irrelevant to their inquiry. To 'scan', by contrast, means to read closely and intently: it's exactly the opposite.
Never mind: the other day an intelligent writer for a pre-eminent news commentary magazine wrote of someone getting behind a podium. I doubt it: a podium (as in podiatry and chiropodist) refers to the foot: its a platform you stand on, the better to address an audience. It's not a lectern: that's the thing you read from once up on the podium.
