The last time the site received a visual redesign was 2012, and the implementation was imperfect. This leaves the site looking outdated, which lowers trust, and decreases session time and depth. This means that potential recurring users brought in from search are lost, possibly permanently. That's a big problem.
Unsurprisingly, users who visit the site rarely stick around to explore and discover the other features. Those who do usually don't create an account, which is a requirement for most of the value-adding features such as ratings, comments, and forum participation.
