And yes, I did notice you didn't ask for 100% useful constructive comments, but only for 50% useful constructive comments. However, it seems like you want comments to be 100% constructive for them to be useful in a wiki.

In my opinion even 1 constructive comment per comment section is enough to make commenting useful.
