Wait, don't I recognize that name? Wait a second... This is THE John Scalzi? When I was a kid I pulled a paperback off of my dad's bookshelf, Old Man's War. Great, take your brain out trashy sci fi, and I mean that in the most positive way possible, it left a big impression on me. Incredible writer, cool that he is still around and has a blog.
He's not only still around, he still writes awesome books.
But yeah, I too was reading without noticing, until I came to the sentence "None of the Scalzis are particularly religious", and thought "wait, Scalzi like John Scalzi? It's not... It is?!"

that's the guy. he's got a new book coming out this month, and is a fun follow on social media too (now on bluesky). i feel like he would be flattered by your description.
You're in for a treat if you haven't read him since OMW. He's one of the more prolific "popular SF" writers around, has won a ton of awards, and usually has a book out about every year or so.
