Today is 4th of July. There’s a Google doodle for it, but you wouldn’t know if you’re from the UK. Google.com is completely different if you are coming from a UK IP address. There is no 4th of July doodle, and what’s worse, you will get entirely different search results, with UK sites having more prominence. The results are slightly different from google.co.uk, as well.
I think it would be better for the regionalised Googles to be the same no matter where you come from, and that includes the US Google.com. What’s the point of the “Go to Google.com” link if going back there isn’t the real American Google?
I haven’t taken a look at Google.cn or Google.com.hk!
