I am a bit saddened to see that the young voted in majority to stay, while older and especially retired people voted to leave. It's understandable, as the old people are more likely to remember the "good old times" before the EU. Also, maybe, they are less likely to be impacted by the turmoil, not needing to look for a job anymore. For the young who will have to live in the future, it's a bit of a slap in the face.
That said, I'm not sure that things will change as much as anybody predicts, considering the UK was already outside of many EU agreements like the Euro and Schengen, and it's probably going to keep close ties to the EU in any case. When most of your trade partners have the same standards, it's generally a good idea to follow the standards.
One thing that is likely to change is that Facebook et al. will find it a lot more difficult not to pay taxes on the revenue they make in UK. That's good, but I'm not sure it's worth the trouble. Also, who knows what will change for the worse?
I am personally disappointed that Nigel Farage is currently happy. Man's an asshole.
