Hi Eric, and welcome to WebmasterWorld.
...regarding the John Mueller comments on NoFollow-ing guest post links, I don't think this applies to simple attribution links for guest posts on high authority sites (note emphasis on high authority).
Yes, I'd noted the emphasis on high authority when I read Matt's comments. As martinibuster describes it, there is a gap there... and I should add that it's a gap not just for sites, but a gap also for posters.
It struck me as I read both articles that it's a gap which has the potential of becoming exponentially wide. To a degree, this probably reflects life's realities... but to turn a lack of compounded authority into a nofollow requirement can be seen as onerous. I understand what it's intended to detect, but the prospect of Bloguin 2.0 is not a pretty picture. ;)
I look forward to what feedback you can get.
