Am I crazy, or do multiple linkdomains at MSN actually produce sensible results? Check out this search:
(linkdomain:seomoz.org | linkdomain:threadwatch.org | linkdomain:seo-scoop.com)
I think it’s showing sites that link to any of those domains, not all three, but still interesting. Someone should play around with the operators some more and see – I think MSN is relatively unguarded about showing link information.
Thanks to squiet for the tip!
