Don't be shy, feedback of any sort is valuable to help us improve your experience in the Developer Community.
One comment that I found recently in a discussion thread:
"... no comment given on how I find the forums since they changed the system a few years back "
What did you like better about the previous system, what do you find confusing, what stops you from engaging?
Sharing your frustration (or joy) will go directly to the team managing the system.
