Googling IM

Okay - trying Google IM - contacted a few people with whom I would be happy to chat - they do not appear to be online (dang, they must have lives....) I have a feeling this could be very useful between librarians at the desk (e.g. please rescue me - there must be an important phone call or something) and friends who need lightening up during the day. I have plenty of screen time and face to face contact all day long and really don't feel the need for much more! However - with the right person - wait and see.
