Wow, so we're reaching 12 of 20 ISPs they tested.  That sounds
kind of high at this point.  They may be crediting SURBL where
other URI blocking technologies are actually being used, such as
AOL's.  OTOH SURBLs are (quietly) used by some of the largest
ISPs and webmail providers on the net at this point.

50% of businesses also sounds too high.  I don't know what the
SpamAssassin and other mail filter deployment is like however.
And the list of applications using SURBLs still continues to
grow, seemingly daily:

I've added the following comment to that article:

"Any legitimate mailer who finds their domain listed on SURBLs is
welcome to submit a report to whitelist at surbl.org. They should
include full and complete contact information for their
organization, information about their sending servers such as IP
addresses, a sample outbound message with full headers and full
message body including URIs, and a description of their
organization and its published mail practices, especially
including published anti-spam policies. We typically unlist
organizations that do not make large-scale use of spam. 

Generally speaking those who don't spam will never get listed on
SURBLs, and our false positive rate is very low.

And yes, we do need to get the FP rate lower, especially on WS.
