I agree with you that you can produce amazing things with the pencil. But it doesn't change the fact that it's a limited medium. Graphite pencil is only one color and it's only limited to one dimension (compare to sculpture, which is three-dimensional). That may sound like silly nitpicking, but I just wish you would realize that all mediums are limited. Some are more limited than others for sure, but I don't think ANSI is much more limited than graphite pencil. People are limited too if they think like you do. It's really offensive that you claim that there's more skill involved in pencil drawing and ANSI. I think pencil drawing is a great medium, but what you're saying is offensive and just not true.
One can produce amazing pictures with pencil and one can produce amazing pictures in ANSI. It requires skill, talent and practice. And yes, working in a limited medium does improve your artistic skills. It's silly to claim it doesn't. I only drew ASCII art for years (I did some acrylic painting on the side, but not that seriously), but I know it greatly improved my artistic skills and it really helped me when I moved to other types of visual art (pixel art, digital painting and many others). I know many great ASCII and ANSI artists who are also very talented in painting, pencil drawing or other mediums. And yes, poetry is a type of art just like pencil drawing and ANSI art. It is entirely relevant in this discussion, whether you want to admit it or not.
Unfortunately I have to say that your point didn't come clear at all. I found your message rather incoherent and irrational. You didn't really form any good arguments, just presented claims that weren't really supported by anything. But I would rather discuss this elsewhere (if you still want to reply to me, if not that's fine too), so please drop me a note or use my journal forum instead, so that we don't clutter up this piece. I just don't understand how you can claim to be so open-minded when you're clearly showing prejudice towards many types of art. To me it appears like hypocrisy.
