Ah! What a coincidence as I was only thinking about doing this (not that I quite know how!) - so thanks for doing it. I spotted a similar one for London's Tower Bridge (@towerbridge) earlier in the week.

Don't you have to worry about doing too many calls to the twitter api or something like that?

I've recently started (evidently so) a little site about the Mersey so I'll get around to giving you a mention soon.

Interesting stuff - I've subscribed to your blog!

Cheers

John
