Thanks!
It would be good to say a bit more about what you are doing or why. Otherwise, this all just disappears into the ether. Your last question forgets that many people in this area are self taught.
As with every survey, your questions leave out as much info as they require.
#1: An increasing number of people are learning “responsive design,” which theoretically obviates the need for separate mobile pages.
#2: The crossover between “television” and “large monitors used for desktops, gaming, television, Netflix, etc” is enormous, making the last choice essentially meaningless. Unless you’re referring to WebTV…
#3: Any designer who doesn’t put content first isn’t doing their client any favors. Everything else shifts back and forth, but content is ALWAYS pre-eminent. Like “CSS over tables,” this question is essentially settled.
#7: This question assumes that the practice of “mobile-first” design is considered best practices by virtually everyone. Not the case.
#9: A lot of designers, including myself, have more than ten years of experience, but design is an avocation (me) or even a hobby. The answers are quite limited.
#10: As noted above, many designers, including some of the leaders in the field, are self-taught.
Not trying to bust your chops, just trying to make your questions and your answers more informative.
