WebmasterWorld used to be brett tabke, now it's a company (doubtless owned by brett!)
it's been WebmasterWorld since i've known it, which is back to 1999.
searchengineworld was also owned by brett and could be under the umbrella of WebmasterWorld inc now, btw the about link on searchengineworld is a 404! :)
>>Curious if that's a typo or if there is some SEO benefit to it.
i imagine mr tabke knows what he's doing!
