Investors could send a specific amount to their account to vote yes.
sure that's how you vote, but that points out the exact problem I am concerned with:
1) if every investor gets 1 vote, you need to have an super-majority of investors watching JD and this thread to know when something requiring a vote happens.
2) if investors get votes proportional to the amount invested, a competing website and buy out and shut down JD very easily by investing lots of money and sending "shutdown" votes
