There are two good blogs that I visit a lot. One is The Immanent Frame, sponsored by SSRC -- it's intellectual, interdisciplinary, but directed to the "general educated reader."
Religion in American History is also directed toward the general educated reader but a very different and more accessible style of commentary.
