one thing that is important i think, keep the one-to-one correspondance between spoken sound and written symbol. Why K and Q ? Why two symbols for "ay" sound (like in "way") ?
that beeing said, i think we already have our own language in the way we use the existing one: complete sentences, precise use of transition words like "and", "then", "but" etc.... and of course, keeping the same subject until everything about it is said AND acknowledged.......
