I reviewed it based on the banner and feedbacks.

Looks good to me! Left a tiny rephrasing suggestion; curious to hear what @samuelsycamore thinks about it, too!

A side note:

As I browsed the website for the last few days, I didn't realize we had the survey notification, until I looked closer at it (at first glance it felt that we didn't). I think it's because it's not clear to me that this is a survey, I stopped reading at the title:

Should do something about it? Probably not, but felt it was worth mentioning this effect, I caught myself not reading the description when the title didn't interest me. So if "survey" is more important than "influence roadmap" in the information hierarchy, we might want to reverse the order between title and description next year.
