Good questions DJSarge

I had a couple of thoughts about #2 also - the chat/IM question. I do see a lot of libraries forbidding chat on the machines and it reminds me of another technology a lot of libraries used to forbid - email. Just a couple of years ago, a lot of libraries were not allowing patrons to use the library computers for email. Now I rarely see that being forbidden. I think the "medium" is being restricted because people don't see value in the "messages" being sent. I, too, am a big fan of chat and use it regularly for professional and personal purposes.
I'm wondering if it would help to share stories of positive experiences with chat - or examples of "important" ways it has been used. When I was working the reference desk, I had a patron using chat to interact with a potential employer. He ended up getting the job. I am a board member of a non-profit where the members are geographically dispersed -- we use chat regularly to have group meetings. What are some other good examples?
Thank you!
