Well, It just so happens that I'm very well adept in the ways of the pen/pencil and paper and my story plots are top-notch.
LOL.. That's a huge claim with no examples of your work.
As for your concerns:
If it appears on those online manga reader sites (i.e. mangafox, mangahere, etc), then you'll probably get more people like you who reads them. Unfortunately, that's not the case and you only see these 'American mangas' posted on deviantart (e.g. shilin.deviantart.com), which only appeal to the 'art enthusiasts', which are a dime in a dozen, really- aka, little to no exposure. Look up Mark Crilley, he has published mangas in America and is pretty fluent in Japanese/lived in Japan, but he doesn't even consider himself a 'mangaka'. I have a feeling your perception of a 'mangaka' are the people who make Naruto, OP, Bleach. Trust me, there are millions of 'mangakas' out there but you probably only know 20 of them at best. Maybe it's just that no American mangaka has a good enough story and has gained enough of a following to become 'famous'.
