This picture is taken from the Facebook group Leicester University Library Toilets Appreciation Society ( here but you have to be registered with Facebook).
The Group was set up to celebrate the toilets in the new David Wilson university library. It probably only confirms suspicions that Facebook (and Social Computing in general) is about trivia - but the library itself does have a Facebook page. As far as I know the University of Sheffield Information Commons isn't on Facebook. Are they missing out on a marketing opportunity or just being sensible?
