The one thing that nobody has mentioned (and actually gets my goat) is that we used to be quite proud of the British Industry/Product, if so many of you host abroad, you are sending money earned in the UK to other countries, do not scratch your head when a UK webhost company is in the news for laying off 50 staff, or the economy is weak and sterling is struggling.
I am getting increasingly wound up at how many people use a foreign country/company to save a few quid a month, and yet will complain about the economy when your grandkids cannot find work, or are staking shelves.
It is not just a choice of where your server is, it is a moral obligation to make a difference to the country you live in, if a product cannot be bought here, you do not have much choice (ie a Spanish omelette

) but you get the point!
I refuse to even buy flowers in supermarkets, as I would rather help keep the independent florists in business, who cares about saving 50p or a few quid, would rather save the country that gave me a free education, free healthcare, lack of military presence on the high street, etc etc!
I really could go on!
My host is a UK company, with UK servers, whether it performs better in searches is down to me, but at least my money is staying where it is earned and not damaging our economy!
