Some new ideas here which may get the conversation going.
I agree with your second point. On the third, I think we are attempting to make a distinction between upvoting comment on your own post and other peoples vote and I am not sure that it the right approach. Self vote on comments should just go. There is no room for it. It is a meaningless social transaction.
As for post self voting, I think that is a harder issue to deal with but I like your suggestion. It is pretty innovative in its approach and could be a good compromise for now.
Thanks, I'd like to see something done but would like the insurance there just in case.
Yes I agree. The insurance in the first point may just convince the SP investors to come on board.
