Interesting that Silicon Valley believes that going to NYC is "going international"!
Obviously the idea is to attract European and Middle East attendance in the London event and I think it is a good choice. Pretty much any airport in Europe flies to London and there are plenty of low cost flights (Ryanair, Wizzair, Vueling, Norwegian, Easyjet, etc) as opposed to e.g. Berlin.
That's a lot of air traffic just for warm beer! But, where do people in London live? I mean with all the Russian and Mideast money buying up all the properties, a little one room condo goes for, what, $20 million?
And, England is a huge step down from where it was when Di was alive.
At times, it appears that some people in England use the language so well it's almost as if they had invented it. But then they mess up their success with some outrageous errors in spelling!
