well, those lists leave me aghast....it makes me think of drug companies and auto makers trying to wring the last coherent combinations of letters out of the language which 'might' be useful in describing their product. Mostly, they are passing the bounds of credibility...and pronounceability...

17 variants on 'Jacardi' make them all sound alike and will eventually be a hindrance to the kid.

(and then there was the couple who were told jokingly that "Urethra" was a nice variant on 'Aretha', and bought it...*sigh*...

(yep, I know...it's not my problem...but..)
