His blog is not attached to any usual, traditional print outfit, but the level of writing at SSS is on par with, if not better, than any print source on the Sox, so I consider him a very credible source about Sox news. I have yet to see anyone at Chicago Now even approach his level of talent and professionalism.
SSS is hosted at SB Nation, not sure if that's still affiliated with SI, but even if so, it's a loose one.
Miller has subscribers (one or two posts a day of the usual six or seven is behind a paywall) and has a journalism background, as well.
I'm not sure if there are similar bloggers who don't have some type of professional or journalistic experience.
