Know of a good application security blog that should be included? Please submit it for consideration here. Lastly, OWASP is free and open so if you're curious how the AppSecNews feed is run then check out the details here.
Many thanks to Jeff Williams for running the AppSecNews feed for the first 8 years. Thanks also to Jim Manico and Sarah Baso for investigating various platforms to restart the new AppSecNews feed!
