A Bunch o' Jihadi Blogs
I've stumbled upon a mother-lode of English language jihadi blogs, including one for Somalia's Al Qaeda front group, Islamic Courts Council. I went through the bulk of them and weeded out anything that was inactive (no posts in two months) or soft-jihadi, ie prayers and refutations. Of the remainin blogs, two characteristics stand out at me:
1) Many of them are new; they've been established since July 2006.
2) Many are hosted by WordPress.
Perhaps WordPress offers a free service, or information about it was posted to a forum or two. I also suspect some of the more hard-core Salafist blogs were established after Global Islamic Media Front (GIMF)'s August 2006 call for more English language jihadi material. However, the question of how many exist and why will need to be answered by someone else, someone who I hope has a research assistant.
