Speaking only for myself, I try to focus on content over presentation. For as long as you have a framework in presenting your content, you can go for a very long time before any significant visual change is needed.
I second what @asterion said. Yes, it's very important to understand that design is only like a first impression and everything else depends on your content. If you revamp again, try to accomodate changes that would reduce friction to uploading content.
relatable. hope to see you back some time! I enjoyed your write up on solar power :]
