I was unable to identify an appropriate thread for AQ / Taliban propaganda, in particular their use of the web. Today FP Blog has two excellent articles by Jarret Brachman:

'Al Qaeda Wants to Be Friends: An insider's tour of the electronic jihad in the Facebook era'

Link:http://www.foreignpolicy.com/article...iends?page=0,0

A longer piece: 'Watching the Watchers: Al Qaeda's bold new strategy is all about using our own words and actions against us. And it's working'

Link:http://www.foreignpolicy.com/article...chers?page=0,0

Which ends with:
What makes al Qaeda's new approach so powerful is that it is now easier than ever for passive jihadi supporters to become active al Qaeda participants, particularly in the West. They no longer need to wait for al Qaeda propaganda. Just like Chesser and the growing number of other American jihadi propagandists operating online, anyone can repost videos, write articles, create Facebook and Twitter accounts, and start blogs filled with content intended to show the world how awful the United States is.

This Power of Truth approach, rooted in finding actual "evidence" of U.S. missteps, has the added benefit of being all the more believable to empirically minded Westerners. Al Qaeda hopes that its online armies of jihobbyists will someday log off and launch their own Fort Hood or Times Square attacks. And eventually, some of them will.
Then in The Daily Telegraph, which I suspect has picked up on another US-based story:
Al-Qaeda magazine published 'tips on how to kill Americans'. A magazine run by the Yemeni group al-Qaeda of the Arabian Peninsula has published a list of tips on how to kill Americans.

I know another, recent thread offered a contrast to AQ's media profile and how it could be criticised:http://council.smallwarsjournal.com/...ad.php?t=11158

Personally I like to emphasise that AQ's appeal for support, let alone action, can fall on "stony ground" as so few take up the "call" and we need to consider the "causes" and the motivation to follow (thanks to Bob Jones here).
