As Chris Shiflett mentions today, there's a new web development security aggregation site that's been launched - Planet-Websecurity.org [feed]. Christian Matthies has headed up the project:

Those of you who have spoken to me recently may already be aware of this project, but for those who don't, I am pleased to announce the launch of Planet Websecurity, founded with the intention to bring together similarly themed news and rants related to Web security and to display them in one place.

Included in the list of blogs/sites aggregated are the blogs of: Chris Shiflett, Robert Hansen, Sid Karunaratne and Christian himself.
