I'd rate 9. This is only because there's no perfection anywhere. Musing has been lit for me. To me, it's not been just about asking and answering questions but getting to learn as well.
I take out time to go through some of the answers provided to questions and it's made me more knowledgeable about certain concepts and ideas that I didn't know about before.
It's definitely been a good experience for me. Indeed, musing has been the most beneficial project I've come across all through my stay since last year September. I'd definitely rate musing higher than the others.
Yep, I can most definitely agree with your statements. The team is filled with professionals who are really working their asses off to reward the right answers, I'm extremely grateful to be here
