[Air-L] Social work blogs & networking

I'm planning a teaching unit for undergraduate students in social work about blogging and online networking related to their field. I'm fairly familiar with the general charity and nonprofit resources, but I'm not familiar with many resources relating specifically to social work. I would appreciate any leads or links to blogs or other online communities that are specifically focused on social work practice generally or on specific sub specialties like youth, families. And in a related question: have there been any articles or research on this subject in any social work journals?
