The annual Online conference has been taking place in the UK. As I am in Australia I haven't got there, obviously, but I can glean some experiences of the conference from the "official" conference blog at:
http://vnuuk.typepad.com/online_information_2005/
and there's also a blog (and swiki) from the UK Electronic Information Group blogged by assorted information luminaries at:

I learnt from this that one of my colleagues at Sheffield University, Mark Sanderson, was giving a talk (he's an Information retrieval expert)!
The actual conference website is at http://www.online-information.co.uk/
and has lots of info on exhibitors.
