It'll be a ton easier when Steve finally publishes his book - then he can be added as a published author.

If you're not that patient, perhaps the avenue is to create an article on the blog itself and argue for its notability. It's probably a lot more widely recognised and referenced than Steve himself.

I note that wikipedia itself refers to stevepavlina.com in the following articles:
