British Starbucks coffee houses took a large stride forward in encouraging Internet use Friday with a change in their Free Wi-Fi service. Similar to the US and Canada, drinkers now just have to visit a single sign-in page, here at BT Openzone, to get access to a hotspot. UK visitors previously had to sign up for a Starbucks Rewards card and login with a username and password, both of which discouraged some from signing in.
