Maybe the reason the UK public are a little behind our Amercian cousins when it comes to being across blogging is because it’s not very ‘British’ for the common man to stand and up and ‘have his say’ on something.
And as you have predicted, I have to agree. But I'm not so sure its quite as simple as to blame our British culture. I feel Geek culture is still kinda of looked down on while America geek culture is much more prolific. I'm not saying that's the only reason either but it like broadband pentration, etc have there part to play in the sum. But lets not forget the ability for the British to quickly change like in the case of House music in the late 80's.
