This might be the section in his post you are looking for:
"I am an active Steemit community member. My blog aims to represent, inform and progress the distributed compute communities surrounding Gridcoin and BOINC. These topics are close to my heart as a medical researcher, where my progress is often slowed by compute limitations. I aim to facilitate a cross-over between the Steemit community and the scientific community to the benefit of both."
You can find out a lot more about his motives here. He definitely has my vote as well :)
I will say it in brief: Community. Intellect. Development
All 3 are very important and are present both in Steemit and Gridcoin
