I was actually going to use the artist analogy myself in my last post, because I too am a bit of an artist. But the way I was going to say it was that for me, hand-coding is like putting paint to canvas whilst my eyes are closed, and then opening my eyes every now and then to see if it's turning out how I am expecting. When WYSIWYGing, I can see what I'm doing as I'm doing it – painting with my eyes open.
Your analogy of saying that when you WYSIWYG, you feel like you're using robotic arms, and saying that you feel there are barriers, sounds to me like you feel you're being restricted as to what you can do... I can perfectly understand that if you started out with Front Page, as you say you did, because that's a very restrictive programme (it prods and pokes you into turning out template pages). But if we're talking GoLive or Dreamweaver, then that's got to be a different story, especially if we're talking modern releases. There's not a thing you can't do with these WYSIWYGers. If you find that statement to be untrue, then it's just a case of you still have to learn more about the programme, and how to use it to its full capabilities. But once you've got it all sussed, then it's plain sailing.
You say tomayto, I say tomarto, let's call the whole thing off :)
No, as just about everyone dabbles a bit in both – it's not a case of whether you CAN do both, it's a case of which you prefer.
