Honestly -- and I will likely get lambasted for this -- but I have to agree with Blockhead to some extent. Anyone who hand quilts or does machine quilting without the assistance of a computer is quilting -- you're the one controlling the output of the needle, and the result is wholly up to you. But if you're using a computer that does all the quilting for you, well you're not really quilting, are you? You're creating a quilt, yes, but you're not actually quilting...the computer is.
To take katiebear's drawing analogy a little further:
a) If I draw a picture on a piece of paper, then I can say that I'm an artist.
b) If I draw a picture on the computer using a graphics program, then I would still call myself an artist. It was my mouse (or graphic pen) strokes that caused the image to be created.
c) If I click a single button within a program, and it draws the picture for me -- am I still an artist? That, to me, is the equivalent of using a computer to do your quilting.
That's just my own opinion, and I hope I won't get too badly stomped on for it. Really, when it comes down to it, if you're enjoying what you're doing and producing, who cares what others think?
