Phone polling is generally more optimistic and seen as a more reliable indicator, but lots of pre-election polls were way off last GE so who knows. It's certainly a nail-biter, you're right there.
I voted Stay a couple of weeks ago. I have very little idea what most of the points made by either side were (it takes ages for the carrier pigeons to get over here), I just can't see how splitting up into smaller and smaller units can be helpful in any way. Also, I'm not sure I can complain about immigration when I'm living in another country.
