I'd already read the witness threads, and didn't find the answers I wanted.
So I went and did a little bit of looking out on the web.
Gridcoin is used to reward participants in the BOINC distributed research project. That's REALLY cool. I used to run BOINC to help with SETI at Home and with AIDS research (my current machine can't run a BOINC client).
That's all I needed to know to think that Gridcoin and Steemit are a good match. I'll be going to cast my votes for these two in just a second.
Great that my post was helpful! I didn't metioned BOINC because it was mentioned in the withnesses' posts. I also run SETI right now on 2 laptops
