1. IN! (numbered because the software prevents starting at 2)

2. I'd say articles based on the site's topic. Target would be sysadmins and people who should be hiring sysadmins.

 * Anything that might be newsworthy in the field -- the RSA compromise would have warranted an article when it happened.
 * General area topics... https://security.stackexchange.com/questions/4032/isnt-oauth-openid-facebook-connect-and-others-crazy-from-a-security-standpoin and https://security.stackexchange.com/questions/4392/is-the-argument-really-over-on-sso could be cited in a document about authentication and centralization vs. decentralization.

3. Hopefully a group of regulars around here. Probably pulling from the 1,000+ rep pool.

4. Starting with Tuesday / Friday sounds good. We should be able to get one article every 2 weeks from four people, I think.
