I agree with @exodo that score of 57/79 and 53/79 (nodebb) doesn't look very good. For some that are judging based on these scores, they would skip and use another app.
I think judging based on those benchmarks alone isn't a great way to determine which software to use.
Yes I agree. When I ask several people to give NodeBB a try as their main app, they first go and check the grades
They sent me this (first one is NodeBB) and said, "why would you use that?"
If I can't even get them to try it, think about others that are also check the grades? This is the same with wp themes that have poor scores. People just skip over them and not use them on sites because they want good grades.
It's hard to get people to look past certain things even after they decide on another app.
