I would just add that you shouldn't just leave any old comment. The more thoughtful and relate-able the comment is the more upvotes you get and therefor the more value it brings you.
so I would say its about quality over quantity. For example I had one comment worth over $2 and 10 worth $0. The one comment added more value to the platform and therefor me.
Indeed.
That's something I also cover in the commenting guide I posted but thank you for pointing it out here for all to see!
Cheers
