I do like this interview question - but I would angle it a little differently. I'm definitely a "senior" web developer - been doing this since '97 - but I couldn't talk fluently about a number of these tags, particularly the exact meaning of each of their properties. However I have used most of them at one point or another and they at least ring a bell. Most of them are tags you throw in at some point to solve some problem or other and forget about them. At least, that's the way my memory works. They are, however, an interesting Rosetta Stone into many different browser quirks and technologies that I would expect a senior developer to know about. If I were to show this list to a candidate, I might ask them to pick one of the tags and talk about a time they used it in a project, to keep it on a level that's comfortable for them and not risk "freezing them up". I would expect the discussion that ensued to give me a good sense of their depth of knowledge in one area. After a few minutes, I'd move on to another topic.
