TfL don’t do a lot right in my eyes. I feel overcharged
often and daily moan about the lack of signs alerting tourists to stand on the
right. But recently they made a social investment that made me smile. Their
homepage proudly proclaimed they were on Twitter.
I wasn't that impressed at the time as I’ve been
following TfL for a while, but clicked the link anyway. They now have Twitter
accounts for every line. Ahead of the Olympic Games this is going to be useful.
