Ireland votes No

I haven't seen much news coverage today -been out and about in the constituency all day. So I'm only now seeing reports of the No vote in Ireland. I guess it means some elements of the treaty have to be renegotiated, but how on earth do they work out which bits people objected to? In news reports yesterday there were posters urging people to vote No, or the EU would compulsorily micro-chip their children (pretty certain that's not actually in the Treaty...) When you have people voting No from the left, from the right, from an informed, from a completely uninformed stance - how on earth do you evaluate that response?
