I can only give you my opinion, nothing more. Use it if you find it useful. Remember, I'm new to animation, so my advice and statements are a bit inaccurate in places.

Obviously, this is not the way to do it. Moho likes a small number of points and supposedly stores its points in a different format than AI. So you have to adjust your methods to this limitation. Don't ask me how, because I'm trying to figure that out as well.
If you think: there goes the particular artistic style I'm used to, all the better. IMO most "artistic styles" are just mannerisms, gimmicks, easy ways to arrive at an image which was popular in the past, but avoids rigorous analysis of the subject at hand. But I guess you completely disagree with me on this.
I also guess that some of you like Moho to be a kind of "general purpose animation program", but I think it is not. I think Moho has limitations, just as any medium (pencil and paper, language, etc.) has limitations you have to live with, because in the short term those limitations are a given fact.
I just find it lots of work & the files still have lots of points - so obviously I must be doing something wrong.
Animation is always a lot of work, so what is your point? If I seem blunt here: it was non-intentional.
Perhaps you could tell me your steps of optimizing .swf detailed drawing file imported from Expression into Flash?

Sorry, I don't have a working version of Flash MX anymore (it expired). I know from past experience that Flash does a pretty good job at reducing the number of points, provided your original drawing wasn't too detailed (so there's room to optimize). This means mostly smooth curves and large surfaces (you know, those visually appealing "blobs").
