personally, I have a dollar amount I'm shooting for, and I'll sell whatever amount of shares to hit that value... if that means I have some shares left over, then I'll keep 'em, but I'm not looking for this as a long-term investment at all
I have a social disorder (although it's not quite full blown Asperger's), and can come across differently than intended...if you're offended by something I've said, I probably didn't mean it with such animosity - please take it with a grain of salt. :)
