For example, one of my favourites is Battleship Island, an abandoned Japanese island which is being slowly taken back by nature.

When Google Maps just came out and blew everyone's mind with their satellite imagery, there are plenty of online communities that focused on finding interesting spots on GMaps, and I was obsessed.
Unfortunately, these communities eventually died out and I never find something similar (admittedly I didn't look too hard, so open to recommendations of similar sites).
This is https://www.reddit.com/r/googlemapsshenanigans/ , but I feel it's way too low effort (almost nothing educational posted, people often just post the screenshot without coordinates and links, no real discussion etc.).
As for your awesome site, I wish there are more descriptions (some only have a title).
I actually run another site [1] which is similar to this one, but dedicated to satellite imagery, and which lets you submit interesting views. It doesn't have a great deal of traffic but I do get a dozen or so submissions per day!

Just one suggestion: How about a small overview map (perhaps zoomable) in one corner, so we can see where in the world we are?
You can also click the Google logo at the bottom left to see the location on Google Maps.
Another fun one is https://randomstreetview.com/ . I've traveled the world multiple times over with that site.
