The Psychotherapy Networkeer site is a big favorite of mine:
http://www.psychotherapynetworker.org

It is an online magazine with in depth articles on things like attachment, grief, connection, psychotherapy, and more. It is targeted at therapists but I find so much of general interest and not just skating on the surface (as do magazines like Psychology Today). There is a print version too but the whole thing seems available online whether you are a subscriber or not.
