Sure, but how many people truly know this? I love knowing about people who are key contributors to the industry. I run into a lot of walls when trying to talk to 99% of my coworkers about any of them.
I feel that if you are in the target audience for this article (deep dive into the behavior and design decisions of the .net GC) then you probably know who Maoni is.
I'm just a sometime mid-level .net dev, and I immediately recognized her name.
That's fair, I usually read these .NET articles that crop up here on HN, though I don't always recognize the names, and I am easily the target audience, but I know industry architects who probably do not know who the author is offhand.
