Perhaps we can maintain a collection of Buddhist blogs which might be of interest for many.
There is Berzin Archives. Although I am not familiar with the whole of it, when it comes to Tibetan Buddhism, it is quiet trustworthy.
I really enjoy the blog Theravadin Blog
I like the fact that it contains a lot of discussion around pali words and a lot of advice on meditation.
I have gotten a lot from Ken McLeod's "Unfettered Mind", especially the podcasts (in the "Teachings & Writings" menu, drill down into "Podcasts"). I also appreciate his approach to translation.
I have long liked http://sdhammika.blogspot.com but in the last time he does not write too often, so I'm not really "up-to-date" with it..
