My preferred DNSBLs (Score 1)

This is a timely article for me. I have been infrequently researching DNSBLs for a few years now, and I am almost finished documenting my findings here: http://www.asspsmtp.org/wiki/DNSBL Its a wiki page for an anti-spam filter that I help develop and maintain this web site for - but the article is completely neutral POV and devoid of any product references. Its my assessment of the DNSBLs that I use and recommend. I would appreciate any thoughtful feed back on the article or recommendations for anything I may have missed. My username on the site is "ME2". Thanks!
