On Gretchen's question about disappearances of library-oriented discussion groups, "where are these professional conversations taking place?" I'm wondering if perhaps conversations are now moving from email lists to social media and becoming more tailored to individual interests. Are people perhaps just 'circling' the librarians most relevant to their professional interests on G+ via sites such as http://findpeopleonplus.com/Occupation-Librarian and https://plus.google.com/115121110877145330939/posts/5aPMJu9wnSN (I'll admit, just in retrieving these links from my +1s I became sidetracked, circled a few more librarians, and shared a post.) Are people 'friending' librarians on Facebook and joining librarian Facebook groups instead of email lists? Or perhaps following tweets and blogs where they used to read email?
