Blogs: The new source of poster quotes

I noticed this (huge) advert for [Windows Phone 7](http://en.wikipedia.org/wiki/Windows_Phone_7 "Windows Phone 7") on my way through [London Bridge](http://maps.google.com/maps?ll=51.5080555556,-0.0877777777778&spn=0.01,0.01&q=51.5080555556,-0.0877777777778 (London%20Bridge)&t=h "London Bridge") this morning. Now, I must have seen it over a dozen times in the last few weeks, but it was only today that what it actually said registered with me.

There was the normal quote from a publication extolling the virtues of the new product – but this was no national newspaper or technology magazine.

A quote. On a huge advert. In one of the mainline commuter stations. In one of the biggest cities in the world.

That feels like another tipping point.
