A new paper on Johnny's "I Hack Stuff" blog requires a subscription. Meanwhile, Sensepost is abandoning their "Regwall" for research papers.
I feel the same way about news paywalls, really. They don't force people to pay, nor do they keep people from getting the news. They just make sure they don't get the news from YOU.
By the way, I threw together a Google Reader "Bundle" of my favorite security feeds. If you use Google Reader (and let's face it, why WOULDN'T you?!) you can easily import these. Beware: it's over 200 RSS feeds, and can get awfully noisy at times.
