How users feel about coop librarians

My post from yesterday about the benefits of being in a chat reference cooperative prompted an interesting question in the comments section that asked how our users feel when they realize they've been connected to a librarian from other college library. Until I can post a more complete reply that question, let me point out that I wrote a brief reply in the comments section.

I'm not quite sure of the best way to reply to comments left at the end of postings. If I post my reply as a comment, will the original commenter think to go back to see if I've written my reply there? Or should I respond by doing an entirely new post, which the original commenter is more likely to see? My messier solution for now: post a new message mentioning the comment and noting my own follow-up comment.
