Mark holds the #1 spot on TeamAnandTech on Folding@Home and anyone who's eyed the forums and/or participated with the project is likely to know that Mark has cancer, which is a huge drive for his donation to the project.
I honestly had no clue what he is going through. I'm on the forums all the time, but it's mostly in OT and occasionally the other forums. I spend more time in Reddit Homelabs and that is why I thought Mark was doing a homelab setup and not anything productive. There are so many people on Reddit doing jack, lol.
Either way, he is doing what is important to him and the community. I can't find any fault in that.
