You normally keep up with staffing updates for writers at random internet blogs? That is mind-blowing, I don't think I ever even read the name of the author of an article intentionally, and when I do it by mistake I forget it 2 webpages down the road.
i've never used twitter myself, but isn't that its purpose? follow people you like because of what they do and get informed by themselves about what happens behind the curtains. OP mentioned being off twitter, maybe they follow the author there and would've seen a tweet about it.
